Lysá nad Labem Castle, Renaissance castle in Lysá nad Labem, Czech Republic.

Lysá nad Labem Castle is a château on a hill in the Polabí lowland, built around a north wing whose thick southeast walls and vaulted cellars retain traces of a Gothic castle. Renaissance work by Bonifác Wolmut and Ulrico Aostalli from 1560 survives as sgraffito fragments and ground-floor vaults; the interiors have housed a retirement home since 1961, while the park is divided into a French garden and an English park.

During the 16th century, Emperor Ferdinand I transformed the original medieval structure into a grand Renaissance residence. This redesign was part of the imperial building campaigns intended to showcase power and prosperity through such palatial constructions.

The castle's name recalls the medieval "tower called Lysá" mentioned in a 1052 document, though its exact site on the hill remains unconfirmed. Since 1961 the interiors have served as a retirement home, so visitors experience the complex through the castle park and the former monastery of the Barefoot Augustinians.

The château interiors have housed a retirement home since 1961 and are closed to the public; only the castle park, split into a French formal garden and an English park, can be visited. The grounds also contain the former monastery of the Barefoot Augustinians and an open-air cinema.

The south facade of the main wing hides a partly preserved Gothic sandstone window surround, found during repairs in 1992 in the second window axis of the upper floor. It confirms that a Gothic castle stands behind the later Renaissance and Baroque work.
