Hradiště Lštění s kostelem svatého Klimenta, Roman Catholic church on a former hillfort in Lštění, Czech Republic.

The Church of Saint Clement stands on a rocky promontory in the area of the former hillfort above Lštění, on the left bank of the Sázava. It is a single-nave building with a flat ceiling, closed on the west by a square tower topped with a shingle-covered onion dome. A nine-are cemetery surrounds it.

Kosmas' chronicle mentions the Lštění hillfort in 1055, when Duke Spytihněv II imprisoned his daughter-in-law there. The Church of Saint Clement likely arose during the hillfort's flourishing; a Romanesque predecessor is assumed. The church was rebuilt in Gothic style in the early 14th century and recorded as a parish church in 1352.

The church is dedicated to Saint Clement, also written Kliment, and stands within the grounds of the former Přemyslid hillfort above the Sázava. Mass is held every odd Saturday. The cemetery around it covers nine ares and holds the grave of Young Czech politician Eduard Grégr.

The site is accessible from the eastern side, with the ascent marked by natural rock formations and historical fortifications. Visitors should expect uneven terrain and steep slopes and wear appropriate footwear.

Excavations have revealed stone walls of varying widths that were stabilized with wooden supports and earth-stone materials. This building technique shows how medieval builders created sturdy fortifications without modern methods.
