The highest point is the hill Rovná at 724 m (2,375 ft) above sea level.

The first written mention of Plánice is from 1144, when it was property of the newly established monastery of Pomuk.

During its history, the town was owned by the noble families of Schwamberg, Sternberg, Rožmitál and Martinic.

It was built by the architect Anselmo Lurago, probably according to the plans of Kilian Ignaz Dientzenhofer.

[8][9] Plánice Castle was originally a fortress, built in the second half of the 16th century.
