The Stone Gate used to be just the City Gate, respectively part of the defensive system elevated in the defence of the Gradec, and today it is great Zagreb's sanctuary. Tower next to The Stone Gate gets at the meaning after the fire which seized the Zagreb on 30th May, 1731. The fire expanded on the street Opatička, through street Kamenita, all the way to the Street Jezuitska. The fire also seized The Stone Gate. All wooden furniture burned on the first floor where was the picture of Blessed Virgin Mary. Framework was the only thing that burned, and the picture survived completely. The widow Modlar decided to finance the construction of the altar under the vault of the City Gate. At that moment, the picture becomes the part of the public city piety. The picture shows Virgin with the Child in her arms. She is carried by two angels, and on the sides are statues of Saint Peter and Paul. Today, the picture is behind an iron fence which was built by Ivaj Juraj Chorta in 1758. On the occasion of the 200th anniversary of the fatal fire in Zagreb, in 1931, Virgin and the Child were given golden crowns. The sanctuary survived a few attempts of demolition, and in 1999 it was decided that the 31th May is the day of city Zagreb, and its patroness is Lady of the Stone Gate. On that day there is a big procession from the Cathedral to the sanctuary. The Stone Gate has been declared protected cultural property, and in 2018 was its last renovation.
