All Saints Church, Gothic chapel in Prague Castle, Czech Republic

All Saints Church is a chapel standing beside Vladislav Hall within Prague Castle and displays characteristic Gothic architectural elements. The building features a simple interior with stone arches, altars, and extensive wall paintings.

The chapel was built in the 14th century under the influence of Peter Parler, one of the most important architects of his time. After a devastating fire in 1541, the building was reconstructed and then blended Gothic and Renaissance styles.

The twelve oil paintings of Saint Procopius's legend on the choir walls were painted by Christian Dittmann in 1668–1669, commissioned by Alois Kinner of Löwenthurm. His gilded wooden tomb, carved by František Ignác Weiss in 1738, shows reliefs of the saint's life and a kneeling figure of Procopius; it was moved from the choir centre to the wall in 1768.

The chapel is generally open to the public only during religious services and concerts, not as part of standard guided tours. It is reached from inside the Old Royal Palace, through Vladislav Hall, so check the day's programme before crossing the castle grounds.

A doorway cut through the wall in 1598 connects the chapel gallery directly to Vladislav Hall, so the land officials could attend services without leaving the palace. The remains of St. Procopius were carried here in a procession on 29 May 1588 and placed in a tomb in the middle of the choir.
