Święty Krzyż Basilica

Święty Krzyż (the Holy Cross) or Łysiec or Łysa Góra (the Bald Mountain), is a place where one of the oldest Polish sanctuaries (more than one thousand years old) is located. The complex consists of monastic buildings and a church where you can visit the Oleśnicki family crypt. The Sanctuary of the Holy Cross Tree Relics is a holy place of Christians and the fragments of the Holy Cross are said to be kept in its chapel.

The exact beginnings of the monastery are unknown, but they are associated with the Benedictine convent from 1135, who from then on resided in the monastery until the shutdown of the order in 1819. There is no certainty about the founder of the monastery, but it is attributed to Władysław Krzywousty and to Bolesław Chrobry (Polish rulers in the 11th century).

Currently, the sanctuary is in the hands of the Oblates Missionaries of Mary Immaculate, who live in the monastery and from 1936 run the novitiate in it. The thousand-year-old church dedicated to the Holy Trinity has been rebuilt several times, and it gained the current Baroque-Classical shape in the eighteenth century. In the Oleśnicki family crypt there is a glass coffin with a corpse, which is considered to be the body of Jeremi Wiśniowiecki.
