The castle which is situated today in Gilău was built in the 15th century. Its castellan is mentioned in a document from 1439. The land was the propriety of the episcopate from Oradea first, and then it belonged to the Transylvanian episcopate. In 1556 the castle became the propriety of the Cabinet.
The castle used to be surrounded by a 20-acres Baroque garden, which already at the end of the 18th century was called Transylvania’s Garden of Eden, as it used to have orange trees, almonds, figs, walnuts and pineapples, too. Today this garden is considered a national monument, and it is the only originally preserved Baroque garden in Transylvania.
