Koberštejn, Castle ruin in Horní Údolí, Czech Republic

Koberštejn is a castle ruin set on a rocky ridge in the Czech Sudeten Mountains, with stone walls that define its former stronghold position. The remaining structures once commanded views across the Black Opava valley and protected a key mountain pass.

The castle was built in the late 1200s to protect gold mining operations in the surrounding mountains and guard a strategic gateway to lands controlled by Wrocław's bishop. It fell into decline as trade routes shifted and local power structures changed over the centuries.

The name Koberštejn is absent from written sources and survived only in local folk tradition; the German form Koberstein is also recorded. From the 16th century until the mid-17th century, robbers were said to have settled in the ruins.

The site is reached by two marked hiking trails: a shorter blue route starting from Horní Údolí or a longer red route from Rejvíz village. Plan your visit for drier months when the paths are easiest to navigate and views across the landscape are clearest.

The castle's name appears in no written source; it survived only in local oral tradition. The first written record, from 1687, calls it abandoned. From the 16th to the mid-17th century, robbers were said to have lived here.
