Trhanov, Cultural monument château in Trhanov, Czech Republic.

Trhanov Castle is a historic château located in the small village of Trhanov within the Plzeň Region. The structure sits among rolling hills and is surrounded by open countryside and forested areas.

Trhanov Castle was built in the Baroque style between 1676 and 1677 by Wolf Maxmilián Laminger of Albenreuth, known as Lomikar, as a summer residence; the village of Trhanov grew up around it. After a fire in 1810 the Stadion family had it rebuilt in the Empire style. It is protected as a cultural monument of the Czech Republic.

The village that grew around the summer residence took its name from the castle, Trhanov. The castle later housed the Špillar Brothers Gallery, and since 2013 a geocache labelled GC4544T has been hidden here for geocaching fans. The nearby church replaced the Chapel of St John of Nepomuk from 1706, built in 1817.

The castle sits in a rural area west of Domažlice and is most easily reached by car. Visitors should be aware that the location is small and remote, so advance planning is helpful.

A geocache labelled "GC4544T" has been hidden here since 2013 for geocaching enthusiasts. The château has been protected as an immovable cultural monument of the Czech Republic.
