Church of the Exaltation of the Holy Cross, Baroque church in Děčín, Czech Republic.

The Church of the Exaltation of the Holy Cross is a Baroque building in Děčín with white walls, tall windows, and decorative details typical of religious architecture from that era. The interior and exterior display the refined style of the Baroque period with carefully crafted ornamental features.

Count Maxmilián of Thun-Hohenstein bought and demolished three town houses and began building the church in 1665; it was completed in 1691 under Jan Arnošt of Thun-Hohenstein. A fire in 1749 damaged the side altars, and fittings were moved here from the more badly damaged parish church of St Wenceslas and Blaise. Since 1826 it has served as the parish church.

The church has served as the parish church since 1826, when the function passed here from the damaged church of St. Wenceslas and St. Blaise. On 14 September 1991 the town of Děčín and the Roman Catholic Church signed declaration documents on shared use of the church, and Mozart's Coronation Mass was performed at the pontifical mass. The church and the adjoining Chapel of Our Lady of the Snows remain the property of the town.

Visitors can enter during visiting hours to view the architecture and attend services if available. It helps to check service times in advance and wear respectful clothing when entering the building.

The foundation stone is a sandstone boulder protruding two metres from the bedrock in the eastern perimeter wall, bearing a Latin inscription consecrated only after the church was finished. The main altar's nearly nine-metre brown Salzburg marble crucifix holds a wooden cross that, per the chronicle legend, came from Janek z Vartenberka's small chapel.
