Křídlo, Castle ruin in Brusné, Czech Republic.

Křídlo is a castle ruin located on elevated terrain near Brusné, with visible stone walls and remains that show traces of its medieval defensive origins. The site preserves enough structure to understand how such fortifications were built centuries ago.

Křídlo Castle was probably built in the first half of the 14th century. The first written record dates from 1365, when Vlk of Dobrotice sold the existing castle to Vilém of Kunštát. In the late 1470s troops of Hungarian king Matthias Corvinus destroyed it during the Czech-Hungarian wars, and by a 1481 sale it was listed as a ruin.

The ruin has been a protected cultural monument since 1973. Its name, Křídlo, means "wing" in Czech, likely referring to the shape of the spur of Barvínek Hill on which it stands. A 2021 monograph by Radim Vrla and Dalibor Janiš summarises research on the site.

Marked hiking trails from Brusné village lead to the ruins on the elevated ground where you can explore the remains. The location is straightforward to reach by following the trail markers from the settlement.

A 2021 monograph by Radim Vrla and Dalibor Janiš, published by the National Heritage Institute in Kroměříž, reassessed the ruins and traced the legend of Machna z Krčmaně and a coin-counterfeiting workshop linked to the site.
