Křemešník, Mountain summit in the Vysočina Region, Czech Republic

Křemešník is a 769 m summit in the Křemešník Highlands, the highest point of the Bohemian-Moravian Highlands, rising about 7 km southeast of Pelhřimov. Its top holds the Baroque Holy Trinity pilgrimage church with arcades, the unfinished Větrný zámek, the Pípalka lookout tower and a hotel.

Silver was mined on the slopes of Křemešník in the 13th and 14th centuries by the Rožmberk and Trčka families; the abandoned shafts later sheltered Franciscan and Ivanite hermits. A wooden chapel dedicated to the Holy Trinity was built in 1555, replaced by a stone chapel funded by Pelhřimov in 1651 and consecrated in 1654. The Baroque pilgrimage church was built in 1710–1720, with arcades added in 1734 and its present form completed in 1750.

The summit holds a Baroque religious complex with the Holy Trinity Church, arcades, and chapels honoring the Coronation of the Virgin Mary and the Dead. These buildings shape how people experience and use this elevated place.

A 52-meter observation tower built in 1993 provides visitors with views extending to Mount Kleť on clear days. The hiking trails to the summit are well-marked and manageable for various fitness levels.

The spring water near the summit flows only during specific times of the year, mainly around Christmas and late July. The water contains traces of silver and shows weak radioactive properties, making it a distinctive feature of this location.
