Under the floor of the Minor Basilica of the of Blessed Virgin Mary from the 14th century in Wiślica there are the remains of two Romanesque churches and at the same time the most valuable monuments of Wiślica.
The first of the churches was founded by Prince Henryk Sandomierski in the mid-12th century. One of the most valuable examples of Romanesque art in the world was found in the crypt, i.e. the ornamental floor, the so-called The Orants album funded by Kazimierz Sprawiedliwy.
The whole was made of gypsum in the years 1175- 1177. The second Romanesque collegiate church founded by the bishops of Cracow was established in the 13th century. It was a huge three-nave church with a rectangular presbytery part and two towers on the west side. Unfortunately, the only remnant that has survived to the present day is the floor made of enameled ceramic tiles, richly decorated with rosettes and the walls that have been partially preserved.
Right next to the Basilica, there is a gothic tenement house founded by the famous chronicler Jan Długosz from 1460, which is currently the best-preserved Długosz’s House in Poland. In its interiors, attention is drawn to the original Gothic polychromes (from 1462-1467) with images of the Risen Christ, Jan Długosz or St. Helena, as well as gothic portals and cellars with an authentic layout of the rooms.
