St. Mark's Church is a Gothic building, one of the oldest churches in Zagreb, in the center of Zagreb's old city. The small church is very simple and lovely, with a mosaic-style roof and the family emblem on it is also very beautiful. The church displays the works of the famous Croatian sculptor Meshtrovic. The colorful pattern consists of two armbands and a substrate, representing the three ancient kingdoms of Croatia in the Middle Ages, and its design idea has a typical Slavic style. The coats of arms of the Kingdom of Croatia and Zagreb are painted on the roof of the church.
