St. Wenceslas Chapel is one of the highlights of the works of the Písek Royal Builders. It is a fine example of early Czech Gothic and under Přemysl Otakar II, its completion ended the construction of the original Zvíkov castle. The Medieval style of the chapel is heightened by mural paintings dating from 1480-1500. panorama, legend
On the stone Gothic altar table is placed a fragment of a later Gothic altar with a relief of the Mourning of Christ, carved 1500-1510 by a Master of Zvíkov Mourning.
