The monumental building of the Franciscan monastery and the Church of the Annunciation of the Blessed Virgin Mary in Klanjec, has been hiding a secret for many years. At the end of the last century, the tomb of the Erdödy family was discovered in the church's womb. The expensive sarcophagi from the 17th century of the Croatian Ban Sigismund Erdödy and the benefactor of the monastery of Varaždin, mayor Emerik Erdödy, were restored in 1999 and 2003 and housed in a specially prepared crypt of the monastery arranged for tourist visits, which has yet to be restored. The sarcophagi are the work of Viennese masters and are performed in the style of early Baroque times. In their mystical form, styled very differently, both sarcophagi tell the story of that time of the Erdödy family's life, and as a rarity of Croatian cultural heritage, they attract the exceptional attention of domestic and foreign visitors.
