Benátky nad Jizerou Castle, Baroque château in Benátky nad Jizerou, Czech Republic.

Benátky nad Jizerou Castle stands on a spur above the right bank of the Jizera, its oldest part the western wing built around 1525 for Bedřich of Donín. A Baroque wing was added under Jan of Werth, and the Schützen family gave the whole its present form at the end of the 17th century. The grounds include the Church of the Nativity of the Virgin Mary and a park with Baroque sculptures of the Sun and Moon, Hercules and Atlas.

The site originated as a monastery in 1349 before being converted into a noble residence in the early 1500s. This transformation involved substantial structural changes that created the building that stands today.

The castle's musical tradition is tied to the Benda brothers, František and Jiří Antonín, born in Staré Benátky, who began their careers in the estate's castle orchestra under Ignác Zikmund of Klenová and Janovice. Bedřich Smetana worked here as a music teacher from 1844 to 1848 and composed his first piano sonata. Memorial halls to Tycho Brahe, the Bendas and Smetana are in the museum.

The castle is open to the public all year round, every day except Mondays. Visitors go through the exhibitions on their own; guided tours are arranged for groups. The ground floor holds Jiří Fiala's private toy museum, while the upper floor holds the collections of the Mladá Boleslav District Museum.

The castle museum holds a collection of objects from Australian Aboriginal peoples assembled by the traveller Josef Polák, a native of the town. It is shown alongside displays on Tycho Brahe, Bedřich Smetana and the Benda brothers, and the ground floor houses Jiří Fiala's private toy museum.
