The first historical record of this locality dates from 1222, but the castle as it looks today dates from 1846-1858, when Prince Alois II of Liechtenstein decided that Vienna was not suitable in the summer and had Lednice rebuilt into a summer palace in the spirit of English Gothic.
The remodelling of the park, which began in 1805 and was completed in 1811, was radical and followed English models. This took place much earlier than the remodelling of the castle building in the “English style”. The new park was created by diverting the River Thaya and digging a new pond there. The excavated material was used to model islands in the pond and the rest of the park was backfilled by 60 to 100 cm. The park of almost 200 ha includes a palm house, a Venetian fountain, Roman aqueduct, a Chinese pavilion, artificial ruins, a minaret, and Johns Castle.
In recent years, the buildings and grounds have been renovated and, in some cases, redesigned. A survey of the tree population showed that there are about 550 species from all over the world. The palm house in Lednice is an eye-catcher. The semi-circular roof is made of cast-iron arches. The greenhouse was designed as an artistic biotope. The restoration was based on ten photographs with the aim of recreating the atmosphere of the 19th century.
Since 1996 by the whole Lednice-Valtice site is a UNESCO World Heritage Site.
