Lukov Castle, Castle ruin in the Zlín Region, Czech Republic

Lukov Castle is a Gothic fortress ruin that crowns the Hostýn-Vsetín Mountains in the Zlín region of the Czech Republic. The stone walls and towers spread across the hilltop in a layout typical of medieval strongholds, with visible sections of ramparts, gateways, and residential structures.

The castle's origins are undocumented; masonry technique points to construction in the second quarter of the 13th century as a royal castle, which Charles IV later bought back from pledge into crown property. The first reliable written mention dates from 1332, when the widow Margaret of the Šternberk family had a deed drawn up. Swedes captured it in 1643 and tore down its defences on leaving; by 1804 it was recorded as a ruin.

The castle gave its name to the village of Lukov below it, and the Šternberk family added "of Lukov" to their title from the 14th century. Since 1983 volunteers of the Friends of Castle Lukov and the Brontosaurus Movement have worked on the ruins, and 35 species of land snails were recorded there in 2004–2006.

The ruin lies about three kilometres from the village of Lukov in the Zlín Region, in the southwest of the Hostýn-Vsetín Mountains. Since 1983 the Friends of Castle Lukov and the Brontosaurus Movement have carried out voluntary restoration and archaeological research there, so some sections may be closed off while work continues.

The castle grounds have been studied by malacologists: between 2004 and 2006, 35 species of land gastropods were recorded there. The ruins also host volunteer restoration camps run by the Friends of Castle Lukov and the Brontosaurus Movement since 1983.
