City gates and defensive towers of the medieval city fortifications have been largely preserved, and are well-worth seeing. The city walls were demolished at the beginning of the 19th century.
A 13th-century castle, on a hill to the east of the town and impossible to miss. It was once the seat of the Earls of Montfort. Today there is a local history museum and some restaurants inside.
Dom St. Nikolaus
The foundations of the church date to the 13th century. After suffering severe damage following serious fires, it was rebuilt in the Gothic style in 1478; it considered to be the most significant Gothic church in Vorarlberg.
Built in 1491 as part of the old city wall. This is also called the 'Salt Gate' (Salztor), as until the turn of the last century salt was stored here.
Cats' Tower
This defensive tower, built in 1507, was once part of the town's fortifications. It is believed to be named after the canons (Katzen) which were kept in the tower, as the targeting devices were shaped like lions' heads. In the early 17th century the building was converted into a bell tower; the current bell was poured in the 19th century and is the largest bell in Vorarlberg. The bell is rung on major holidays and on Fridays at 15:00 (Todesstunde Christi: believed to be the hour of Christ's death).
Thieves' Tower
Built in the 15th century, this was once, as the name suggests, a prison. The city walls which once connected it to the other towers were demolished several decades ago.
Powder Tower
The Pulverturm was built in 1460 and is the oldest of the city's four towers. As the name suggests, gunpowder was stored here. Today the tower is used as a meeting place by a local association.
