'''Museum of the City of Zagreb''' (20 Opatička Street) was established in 1907 by the Association of the Braća Hrvatskog Zmaja. It is located in a restored monumental complex (Popov toranj, the Observatory, Zakmardi Granary) of the former Convent of the Poor Clares, of 1650. The Museum deals with topics from the cultural, artistic, economic and political history of the city spanning from Roman finds to the modern period. The holdings comprise over 80,000 items arranged systematically into collections of artistic and mundane objects characteristic of the city and its history.
