Líšnice, Fortified house in Líšnice, Czech Republic.

Líšnice is a ruined medieval fortified house on a wooded rocky spur above the Líšnička stream east of the village. Its core, about 37 × 32 m, keeps part of a rubble-stone ring wall, a bailey and outer defences; two ditches with ramparts surround it, the outer 13–16 m wide and 4 m deep, the inner 15–17 m wide and 6 m deep.

The fortified house was built in the first half of the 14th century, probably at the turn of the 13th and 14th centuries, by the lords of Kunštát on a wooded rocky spur above the Líšnička stream. It guarded the trade route between Olomouc and Moravská Třebová. First mentioned in 1353, it was captured three times between 1417 and 1436 and destroyed after the raid of Margrave Albert of Moravia in 1436; in 1494 it was recorded as deserted.

The name Líšnice comes from the village below; the fortress itself served the lords of Kunštát, who built it to guard the trade route between Olomouc and Moravská Třebová. Its remains lie in a mixed forest, and the site is a protected archaeological locality.

No marked hiking trail leads to the ruin. From Líšnice, follow the local road toward Starý Mlýn, turn right along the stream to the quarry, then continue on worn footpaths up to the site. The remains lie in mixed woodland on a rocky spur above the Líšnička valley.

The site is a ruin, not a standing house: only part of the core survives, about 37 × 32 m, with fragments of a rubble-stone ring wall, a bailey and outer defences. Two ditches with banks surround it, the outer 13–16 m wide and 4 m deep, the inner 15–17 m wide and 6 m deep.
