The church on Resslova Street, built in the 18th century, was originally consecrated to St. Charles Borromeo. There are still frescoes inside that depict scenes from this saint's life. However, in 1783, during Emperor Joseph II's reforms, the church was closed. The army used the building for many years. Only in 1933, after a long reconstruction, was the building transferred to the Czech Orthodox Church. It was re-consecrated and began to be called the Cathedral of Saints Cyril and Methodius.
