Dobrovo Castle stands in the heart of the Slovenian Collio (Brda). Built in the 17th century by the Counts Colloredo, it was later acquired in 1789 by Giovanni Battista II Catterini. At the end of the 19th century, Spanish Count Silverio de Baguer renovated it and set up a rich museum collection, which was partially donated to the Provincial Museums of Gorizia before the Great War. During the World Wars, the castle suffered looting and was used as a military hospital.

Renovated by the Goriški muzej between 1979 and 1991, the castle now houses museum and exhibition spaces. The structure, with angular towers and a symmetrical Renaissance-style layout, has a Baroque character accentuated in the window openings and central axis. The interiors include frescoes by Clement Del Neri (1894) and other works in the main rooms.
