Chapel of the Holy Cross, Gothic chapel in Kateřinky, Czech Republic.

The Chapel of the Holy Cross is a Gothic brick chapel on an octagonal plan, founded in 1394. Its lower part is quarry stone, separated by a stone cornice from the upper part of red brick with glazed headers. Two moulded portals, irregular windows and walled openings remain; inside, a wooden ceiling covers the space where a star vault may have stood.

Founded in 1394 by Duke Přemek I of Opava as a funerary chapel, it was used for Protestant services by Swedish troops during the Thirty Years' War, hence the name Swedish Chapel. Between 1785 and 1789 it became princely property and served as a granary, its interior split into two extra floors; a fire on 16 February 1859 destroyed the remaining wall paintings. From 1868 to 1869 a new cemetery was laid out around it, and in 1907 it was bought and repaired, with restorations by Romana Balcarová in 1995.

Locals call it the Swedish Chapel because Swedish Protestant troops held services here during the Thirty Years' War. The name survives in everyday use, though the building later served as a granary and from 1868 as a cemetery chapel for the new graveyard laid out around it.

The chapel stands in the Kateřinky district, surrounded by the cemetery laid out around it in 1868–1869, so it is reached through the graveyard grounds. Look for the slate roof and the stone cornice dividing the quarry-stone base from the red-brick upper walls. The interior is covered by a wooden ceiling, not the original vault.

During the Thirty Years' War the chapel hosted Protestant services for Swedish troops, which earned it the popular name Swedish Chapel. A band of Gothic lettering uncovered during the 1907 restoration hides the date 1514.
