Kirche der Kreuzerhöhung

This Gothic basilica serves as a parish church and titular cathedral, with history reaching back to the 14th century and an architectural inception around 1400. Recognized as a Cultural Heritage Site, it forms a key part of the local "seven churches" ensemble. The building is situated within the historical district near the former Piaristic monastery and the chateau, maintaining a historical connection to the nearby monastery gardens.

The interior features significant architectural elements, including 16th-century galleries (empory) and elaborate baroque furnishings. A modern organ, installed to facilitate the interpretation of music across all historical style periods, is a central feature of the church's musical equipment.

As a venue for both religious and cultural events, the church hosts regular masses as well as performances of spiritual, choral, and chamber music. It remains a significant landmark of ecclesiastical heritage and a center for local spiritual life.
