Josefov Fortress

Jaroměř, Czech Republic

Josefov Fortress is a large historic defence complex of 18th-century military architecture in Jaroměř, Czech Republic. It was built between 1780 and 1787. Together with Terezín fortress, it was built for protection against attacks from Prussia, but its military importance, like other such fortresses built across Europe, was minimal as decisive battles were often fought elsewhere. In 1948 it became part of the town of Jaroměř.


Designed by the French architect Claude Benoît Duhamel de Querlonde and fortified by octagonal-shaped, bastion-like brick walls extending over 289 hectares, the fortress is a system of fortifications in the form of an amphitheatre with extensive three-storey deep underground corridors formed in cretaceous rocks, and running through a labyrinth of 45 kilometers, the likes of which cannot be found anywhere else in Europe. It had three distinct sections - the main fortress with its residential and public function, the lower Crown fortress with a fortified island, and a forward redoubt in Brdce fortress. The town had four gates. The dominant part of the whole Josefov Fortress is the Empire Church, which was built between 1805-10. It was designed by Heinrich Hatzinger, Julius D’Andreis and Franz Joseph Fohmann. Before that, there was a fountain in the same place, which was made by the Czech J. Malinský in 1817.

The Josefov fortress was originally named Ples, and only later, in 1793, was it renamed Josefov. In 1948 the fortress town was incorporated into Jaroměř and today it is an urban monument reservation preserving 18th-century military building techniques and classicist urbanism.


Over the years, the fortress has been converted into a residential district. The biggest extreme metal music festival in Central Europe, Brutal Assault, takes place here each August, with the music stages built against the outer walls. Metalheads from all over Europe occupy the fortress for four days each year.

The Pilgrimage Church of Wies (Wieskirche) is an oval rococo church, designed in the late 1740s by Dominikus Zimmermann. It is located in the foothills of the Alps in the municipality of Steingaden.

The sanctuary of Wies is a pilgrimage church extraordinarily well-preserved in the beautiful setting of an Alpine valley, and is a perfect masterpiece of Rococo art and creative genius, as well as an exceptional testimony to a civilization that has disappeared.

The hamlet of Wies, in 1738, is said to have been the setting of a miracle in which tears were seen on a simple wooden figure of Christ mounted on a column that was no longer venerated by the Premonstratensian monks of the Abbey. A wooden chapel constructed in the fields housed the miraculous statue for some time. However, pilgrims from Germany, Austria, Bohemia, and even Italy became so numerous that the Abbot of the Premonstratensians of Steingaden decided to construct a splendid sanctuary.
