Collegiate Basilica of the Birth of the Blessed Virgin Mary, Wiślica

[3] Construction of the first Romanesque collegiate church in Wiślica, the town which in the early Middle Ages was one of the biggest administrative centers of southern Poland, was initiated by Prince Henry of Sandomierz in the mid-12th century, and finished in the second half of the 12th century by his brother, Casimir II the Just.

In western part of the nave, there was a gallery or choir loft and under the presbytery, there was a crypt, whose remains still can be found.

[4] It was one of several churches built by the ruler of Poland as atonement for his murder of the vicar of Wawel Cathedral, Marcin Baryczka.

Under King Ladislaus II Jagiello (1386–1434) the collegiate church in Wiślica was adorned in frescoes, which have come down to us in a very poor condition.

After the war, when Wiślica became part of the Second Polish Republic, the damage was repaired with help of Professor Adolf Szyszko-Bohusz, a renowned architect of the Jagiellonian University.

Above the portal, there is a low relief commemorating King Casimir III and Jan Bodzanta, Bishop of Kraków.

The Northern portal was built in the second half of the 14th century, with several eagles and coats of arms of Polish provinces.

In the presbytery, there are the remains of several post-Byzantine wall paintings, made by Master Hail, an Orthodox painter from Przemyśl between 1397 and 1400.
