Templštejn Castle, Castle ruin in Dolní Heřmanice, Czech Republic

Templštejn Castle is a ruin on a forested spur above the Oslava valley, 1.5 km west of Dolní Heřmanice. Only the stump of a square bergfried survives, 1.5 m thick and 5 m high over a 4 m length, along with traces of the moat and a paved approach path to the east.

Templštejn was probably built at the turn of the 13th and 14th centuries as a late medieval watch castle above the Oslava. The lords of Lipé later held it, and Čeněk of Lipé is recorded there on 24 April 1417 in a dispute with the Žďár abbot. From the first half of the 16th century it was considered demolished; with no record of conquest, it is assumed it burned down and was never rebuilt.

The name Templštejn is modern and has no historical basis; locally the site is known simply as Hrad (the castle). Popular tradition links the name to the Knights Templar, but no evidence shows the order built it. Guides and maps often confuse it with the larger Templštejn ruin near Jamolice above the Jihlava, 28 km to the southwest.

The ruin lies 1.5 km west of Dolní Heřmanice on a spur above the Oslava, with the Eliášova Myslivna forest lodge below to the northwest. The whole area is covered by coniferous forest, and remains of a paved access path are visible on the eastern side. The site is known locally simply as Hrad.

The visible masonry is a 1.5-metre-thick, 5-metre-high stump of the bergfried, four metres long, and the castle ditch survives in the terrain. The site is often confused with the larger Templštejn ruin above the Jihlava, 28 km to the northeast.
