Lendava Castle, Medieval castle on hilltop in Lendava, Slovenia.

Lendava Castle is a fortified structure standing on a hilltop in the Municipality of Lendava, Slovenia. The building displays an L-shaped layout with a central tower on its southwest side, thick buttresses reinforcing the walls, and a mansard roof covering two upper levels.

A 1192 charter records (Alsó)Lendva passing into the hands of the Hahót (Hahold) family, whose Hahót-Buzád branch made the castle and town its seat in the first half of the 13th century. After the Mongol invasion and the sieges of Ottokar II of Bohemia, Stephen I of Alsólendva had the building fully renewed; in 1272 a Hahót called himself dominus de Lindau. The male line died out in 1645, and the estate passed through the Nádasdy family to the crown after Ferenc Nádasdy's execution in 1671. Pál Esterházy received it and had it rebuilt in Baroque form in the early 18th century, in an L-shaped plan said to honour Emperor Leopold I.

The castle now houses gallery and museum spaces where visitors can see local collections and artworks on display. Walking through the rooms, you encounter archaeological artifacts and exhibitions about the region's past.

The castle functions as a museum and gallery open to visitors interested in exploring its exhibitions and collections. Allow adequate time to walk through the rooms and view the displays at a comfortable pace.

The L-shaped plan is said to honour Emperor Leopold I, whose initial it forms. The castle never fell to the Ottomans: in 1603 its 800 defenders with 12 cannon, supported by 500 horsemen and foot soldiers outside and 80 men in an outer fort, repelled the siege.
