Biskupija is the most important archaeological site of Croatian national history and the largest medieval archaeological site in Croatia. Archaeological findings from that area date from the late 6th and the early 7th centuries to the 11th century- the period when Croatian people created their first state entity and accepted the Christianity. Paintings from this period, the recognizable ornaments and inscriptions are the foundation of Croatian national identity. Saint Mary's Church is where the earliest representation of Virgin Mary in the Croatian art was found. On its foundations, based on the draft of Croatian sculptor Ivan Meštrović, a memorial church was built between 1937 and 1938.
