Chapel of Saint Procopius, Religious chapel in Zásada, Czech Republic.

The Chapel of Saint Procopius is a Baroque rectangular building with a semicircular apse and a small bell turret topped by an onion-shaped roof. Its interior is Baroque, except for a 20th-century altarpiece of Saint Procopius by a local painter. It is the second-largest chapel in the Czech Republic.

The chapel was built between 1747 and 1749 at the expense of Jan Šourek, then the village reeve and innkeeper, following plans by master mason Jiří Folkert of Železný Brod. A local legend says Šourek founded it in gratitude after bandits attacked him and his servant hid his money in bushes by an oak. In January 1751 the village of Zásada bought adjoining plots from the Návarov estate for holding events.

The chapel is dedicated to Saint Procopius, to whom it was consecrated after its completion in 1749. From then on, pilgrimages and parish fairs (posvícení) were held here, and until 1859 Passion plays were performed at the chapel. The interior is Baroque; the altarpiece of Saint Procopius dates from the 20th century and was painted by a local artist.

The chapel sits on gently elevated ground and is best reached on foot through the village. Wear sturdy shoes since the approaches can be uneven, and check ahead for access times as this is an active religious site.

The chapel owes its existence to a legend: the suddenly wealthy reeve Jan Šourek was ambushed by bandits, and his maid hid his money in bushes by an oak. In gratitude for surviving, he had the chapel built on that spot between 1747 and 1749.
