Koleč Castle, Baroque château in Koleč, Czech Republic.

Koleč Castle is a baroque structure with a white facade, symmetrically arranged windows across two levels, and a central entrance portal. The complex includes a chapel that developed into a separate building.

The castle was built between 1711 and 1713 on the site of a 16th-century fortress for the Ubelli of Siegburg family. In 1715 Bishop Daniel Josef Mayer of Mayern, later Archbishop of Prague, consecrated the castle chapel. The Ubelli line died out in 1799 and the estate passed to the related Bohuš of Otěšice family.

The Chapel of the Holy Trinity in the east wing was consecrated in 1715 by Bishop Daniel Josef Mayer of Mayern, later Archbishop of Prague. Enlarged in 1898–1899, it served the spiritual needs of the whole village, and weddings are held there again today.

The castle operates as a museum while undergoing restoration work, so check the website zamekkolec.cz before planning your visit. Current conditions and opening details are available there for planning purposes.

The Chapel of the Holy Trinity occupies the castle's east wing and was enlarged in 1898–1899; it served the spiritual needs of the whole village, not just the estate. Weddings are held there again after partial repairs.
