Overview
Welcome to Baden, a small city on the Limmat river in the canton of Aargau that has been a spa destination for over two thousand years. The Romans knew it as Aquae Helveticae, and they came here for the same reason people come today: the hot thermal springs that rise from deep within the earth at temperatures of up to 47 degrees Celsius, making them the hottest in Switzerland. But Baden is far more than a spa town. Its dramatic old town, perched on a cliff above a narrow gorge of the Limmat, its ruined castle, and its surprisingly vibrant cultural scene make it one of the most rewarding small cities in northern Switzerland. On this walking tour, you will discover Roman baths, medieval lanes, a ruined fortress, and the story of a town that has been soothing weary bodies for two millennia.
Let us begin.
Stop 1: Baden Railway Station and the Approach
Start at the Baden railway station. Walk south along Bahnhofstrasse toward the old town.
Baden sits on the Limmat river, about 25 kilometres northwest of Zurich, and it has been an important settlement since Roman times. The name Baden simply means "baths," and it tells you everything about the town's raison d'etre.
The Romans established Aquae Helveticae here in the first century AD, building bathhouses over the hot springs that bubble up from a geological fault line in the Limmat gorge. The thermal water, rich in sulphur, calcium, and other minerals, was prized for its healing properties, and the settlement became one of the most important spa towns in the Roman province of Helvetia.
Baden's importance continued through the Middle Ages. The Swiss Confederates held their Diet, the Tagsatzung, in Baden from 1426 to 1712, making it effectively the political capital of the old Confederation for nearly three centuries. The delegates who gathered here to debate matters of national importance were also enthusiastic bathers, and the combination of politics and hot water became a defining feature of Baden's character.
Walk along Bahnhofstrasse toward the Limmat and the old town. The river gorge opens before you as you approach.
Stop 2: The Old Town (Altstadt)
Cross the Limmat and enter the old town, climbing the narrow lanes up the hillside.
The old town of Baden is dramatically situated on a cliff above the narrow gorge of the Limmat. The streets are steep, narrow, and atmospheric, winding between buildings that date from the fifteenth to the eighteenth centuries. The medieval character of the quarter is remarkably well preserved, with half-timbered houses, stone archways, and small squares opening unexpectedly along the climbing lanes.
The Landvogteischloss, the ruined castle that crowns the hilltop above the old town, is the most prominent landmark. We will visit it shortly, but for now, enjoy the old town itself. The buildings lean in over the narrow lanes, almost touching across the street at upper-floor level, and the effect is intimate and slightly claustrophobic, a world away from the open spaces of the modern town below.
Baden's cultural life is surprisingly rich for a town of its size. The town has a long association with the arts, partly because of its proximity to Zurich and partly because of its spa tradition, which has always attracted creative and intellectual visitors. The Royal Spa Hotel, the Verenahof, and other establishments hosted distinguished guests including Goethe, Nietzsche, Thomas Mann, and Hermann Hesse at various points.
Stop 3: The Landvogteischloss (Bailiff's Castle) and Stein
Climb to the ruins of the castle above the old town.
The castle ruins that crown the hilltop above Baden are the remains of the Stein, a fortress that played a significant role in Swiss political and military history. The name Landvogteischloss refers to its later use as the residence of the Bernese bailiff, or Landvogt, who governed the region on behalf of Bern from the fifteenth to the eighteenth century.
The original castle was built by the Counts of Lenzburg in the eleventh century and later passed to the Habsburgs. The Habsburgs used it as a power base in their conflicts with the Swiss Confederates, and it was repeatedly besieged and damaged during the wars that led to Swiss independence. The castle was finally destroyed during the French invasion of 1712, and it has remained a romantic ruin ever since.
The ruins are evocative: crumbling walls, empty window openings framing views of the river and the town below, and fragments of towers rising against the sky. From the highest point of the ruins, the view encompasses the Limmat gorge, the old town rooftops, the modern city beyond, and the hills of the Aargau countryside.
The Historisches Museum Baden is housed in the restored Landvogteischloss building at the base of the ruins and contains exhibits on the town's history, from Roman times to the present.
Stop 4: The Limmat Gorge and Holzbrücke
Descend from the castle and walk to the Holzbrücke, the covered wooden bridge spanning the Limmat.
The Limmat at Baden flows through a narrow gorge cut into the limestone bedrock, and the thermal springs emerge from the fault line at the bottom of this gorge. The hot water rises to the surface at a temperature of up to 47 degrees Celsius, the hottest natural springs in Switzerland.
The Holzbrücke, a covered wooden bridge, spans the Limmat at one of the narrowest points of the gorge and offers views down to the rushing water below. Wooden bridges have crossed the Limmat at this point for centuries, and the current bridge, though restored, maintains the traditional covered design.
Standing on the bridge, you can sometimes see the thermal water entering the river, visible as a shimmer or a slight change in water colour where the hot springs meet the cold river. The sulphurous smell that occasionally drifts from the springs is a reminder of the geological forces at work beneath your feet.
The Limmat gorge is also home to a number of small caves and grottoes that were used by the Romans for bathing. Archaeological excavations in the area have uncovered Roman coins, jewellery, and votive offerings left by bathers who believed the springs had divine healing powers.
Stop 5: The Bäderquartier (Spa Quarter)
Walk south along the Limmat to the Bäderquartier, the historic spa quarter.
The Bäderquartier, the spa quarter, is the oldest continuously used bathing area in Switzerland, and its history spans over 2,000 years. The quarter is located on both banks of the Limmat, where the thermal springs emerge from the ground.
The Romans built elaborate bathhouses here, and fragments of their facilities have been uncovered by archaeologists. During the Middle Ages, the springs were managed by the town authorities, and a series of bathhouses were built to serve both local residents and visitors. The spa tradition flourished particularly during the period when the Swiss Diet met in Baden, as the politicians took advantage of the hot water between sessions of debate.
By the nineteenth century, Baden was one of the most fashionable spa towns in Switzerland, with grand hotels and bathhouses catering to wealthy visitors from across Europe. The tradition of spa bathing declined in the twentieth century as medical science moved away from hydrotherapy, but in recent years there has been a revival of interest.
The Bäderquartier has been the subject of a major redevelopment project. The new thermal baths, designed by the architect Mario Botta, opened in 2021 and represent a dramatic reimagining of the spa quarter. The building features a series of pools filled with the natural thermal water, set in a contemporary architectural space that pays homage to the ancient bathing tradition while offering thoroughly modern facilities.
Stop 6: The Stadtturm (City Tower)
Walk back into the old town to the Stadtturm, the city tower on the Kirchplatz.
The Stadtturm, the city tower, is a medieval tower that has served as a watchtower, a clock tower, and a prison over its long history. It stands in the Kirchplatz, a small square in the heart of the old town, and its clock face is a familiar landmark.
Next to the tower is the Stadtkirche, the town church, a Reformed church dating from the fifteenth century. The church is relatively plain in the Protestant style but has a commanding position above the gorge.
The old town around the Kirchplatz is the most densely built part of Baden, with narrow lanes, steep staircases, and buildings that seem to have been squeezed into every available space on the hillside. The effect is picturesque and slightly labyrinthine, and it is easy to lose your bearings, though you are never more than a few minutes' walk from the river.
Stop 7: The Langmatt Museum
Walk north from the old town to the Villa Langmatt on Römerstrasse.
The Langmatt Museum, housed in a charming Art Nouveau villa built in 1900 for Sidney and Jenny Brown-Sulzer, holds one of the finest private collections of French Impressionist paintings in Switzerland. Sidney Brown was a co-founder of the industrial firm Brown Boveri, later ABB, which was headquartered in Baden and became one of the largest engineering companies in the world.
The collection includes works by Renoir, Monet, Cézanne, Pissarro, Sisley, and Degas, displayed in the elegant rooms of the villa as they were during the Brown family's lifetime. The intimate scale of the house and the quality of the art create a museum experience that is personal and deeply pleasurable.
The Langmatt's garden is also beautiful, with mature trees and a peaceful atmosphere that provides a welcome contrast to the energy of the old town.
Stop 8: The Limmat Promenade and Industrial Heritage
Walk along the Limmat promenade back toward the station.
The Limmat promenade offers a pleasant riverside walk connecting the spa quarter with the modern town centre. The Limmat here flows strongly, the same river that continues southeast to Zurich and eventually joins the Aare near Brugg.
Baden's industrial heritage is visible along the riverbanks. Brown Boveri, founded here in 1891 by Charles Brown, a British-born engineer, and Walter Boveri, a German-born industrialist, grew into one of the great Swiss industrial enterprises. The company was a pioneer in electrical engineering, producing generators, transformers, and railway motors that powered Switzerland's electrification in the early twentieth century. Its merger with the Swedish firm ASEA in 1988 to form ABB created one of the world's largest power and automation companies, and ABB still maintains a significant presence in Baden.
The industrial legacy extends beyond ABB. The power of the Limmat attracted other manufacturers to Baden, and the town became an important industrial centre in the nineteenth and early twentieth centuries. The former factory buildings, some of which have been converted into cultural spaces and residential lofts, are architectural reminders of this productive era.
Stop 9: The Cultural Quarter and Royal Theatre
Walk toward the area near the Royal Baden Hotel and the Kurtheater.
The Kurtheater Baden, the spa theatre, built in 1892, is one of the most charming small theatres in Switzerland. Designed in the Neo-Baroque style, it was intended to entertain the guests of the spa, and its intimate auditorium, seating just 450 people, has excellent acoustics and a warm, elegant atmosphere. The theatre hosts a programme of drama, music, and comedy throughout the year and is an important cultural venue for the region.
Baden's cultural life is surprisingly rich. The Historisches Museum, housed in the Landvogteischloss, provides an excellent overview of the town's history. The Museum Langmatt, which we visited earlier, adds Impressionist art to the mix. And the Stiftung Langmatt garden, with its English-style landscape design, is a peaceful retreat.
The town also hosts an annual film festival, the Fantoche International Animation Film Festival, which has grown since its founding in 1995 into one of the most important animation festivals in Europe. The festival draws filmmakers, animators, and audiences from around the world and adds a contemporary creative dimension to Baden's cultural identity.
Stop 10: The Roman Legacy and Archaeological Sites
Walk to the area near the Bäderquartier where Roman remains have been found.
The Roman presence in Baden was substantial, and archaeological finds have revealed the extent of their settlement. The thermal baths of Aquae Helveticae were among the most important in the Roman province of Helvetia, and the remains of Roman bathhouses, including hypocaust heating systems, mosaic floors, and votive altars, have been uncovered during various construction projects.
The Romans were sophisticated bathers. Their thermal complexes typically included a series of rooms of different temperatures: the frigidarium, the cold bath; the tepidarium, the warm bath; and the caldarium, the hot bath. Bathers would progress through these rooms, enjoying massage, exercise, and socialising along the way. The Roman bath was as much a social institution as a hygienic one, serving as a community gathering place where business was conducted, news was exchanged, and friendships were maintained.
The votive altars found in Baden are particularly interesting. These small stone altars were dedicated by grateful bathers to the gods and goddesses associated with healing waters, including Hygeia, the goddess of health, and various local deities. The inscriptions on these altars provide valuable information about the people who used the baths: their names, their origins, and the ailments they hoped to cure.
The continuity of bathing at Baden is remarkable. The same thermal springs that attracted Roman bathers two thousand years ago still flow today, at the same temperature and with the same mineral composition. Few places in Europe can claim such an unbroken connection between ancient and modern cultures of healing.
Closing Narration
Our walking tour of Baden has taken you through a town where the waters of healing have flowed for two thousand years, where a medieval old town clings to a cliff above a limestone gorge, and where a ruined castle tells the story of the struggles that shaped Switzerland.
Baden is a town of layers: Roman baths beneath medieval streets, a spa tradition that has been renewed for the twenty-first century, and an industrial heritage that grew into a global enterprise. Visit the thermal baths. Climb to the castle ruins. Walk through the old town lanes. And visit the Langmatt, where Impressionist masterpieces hang in the rooms of an Art Nouveau villa, a reminder that culture and industry have always walked hand in hand in this remarkable little city.
