Don't miss the City Museum in the 17th-century Convent of St Clair, which is built along the eastern wall of the town. Since 1907 the convent has housed a historical museum presenting the history of Zagreb in documents, artwork and crafts, plus interactive exhibits that fascinate kids. Most interesting is a scale model of old Gradec. Summaries of the exhibits are posted in English and German in each room and evocative music accompanies your visit.
