Bolfánek, Observation tower in Chudenice, Czech Republic.

Bolfánek is the 45-meter tower of the former Church of St. Wolfgang, standing on Žďár hill (583 m) about one kilometer southwest of Chudenice. Its viewing platform is reached by 138 steps, and the tower retains traces of the demolished church nave and foundations.

The Baroque pilgrimage church of St. Wolfgang was built between 1722 and 1729 for František Josef Czernin to plans by František Maxmilián Kaňka. Suppressed in 1786 under Joseph II's reforms, it was looted and demolished by 1810, leaving only the tower. In 1844–1845 mason Jan Kubát of Pušperk rebuilt the tower as an observation tower with a neo-Gothic roof and five small turrets modelled on the Black Tower in Klatovy.

The name Bolfánek is a Czech form of Wolfgang, the Regensburg bishop who is said to have spent a night on Žďár hill in 973. Pilgrimages were held here every 21 October, and a hermit housed in a lodge designed by F. M. Kaňka helped the priest with services and confessions.

The tower stands on Žďár hill, just over a kilometre southwest of Chudenice. The viewing platform is reached by 138 steps, and the tower is a protected cultural monument. The site is not staffed, so check locally before climbing.

The tower's neo-Gothic roof with five small turrets, added in 1844–1845 by mason Jan Kubát of Pušperk, was modelled on the Black Tower in Klatovy. Beside it stands the Šlépějová Chapel, built in 1772 over a rock said to bear the footprints and crozier mark of Saint Wolfgang.
