Schattenburg Castle

Highlight • Castle

The historic Schattenburg
The Schattenburg towers over the city and was the seat of the Counts of Montfort until the end of the 14th century. The keep, the highest part of the Schattenburg, is a viewing platform and allows a view over the whole of Feldkirch. It is particularly interesting for castle enthusiasts, as the complex has been preserved almost unchanged despite some extensions. Here you will also find the Schattenburg Museum and an inn, which invites you to linger and is famous for its giant schnitzel.
