Miercurea Ciuc Roman Catholic Church, Roman Catholic Church in Miercurea Ciuc, Romania

Miercurea Ciuc Roman Catholic Church, known as the Millennium Church, was built in 2003 next to the 18th-century Baroque Saint Cross Church. Its two towers carry five crosses above each gateway, and the gates repeat motifs from the old church. The interior is conical, like a tent, topped by a 5×5 m glass cupola above the altar.

The building was completed in 2003 and follows modern architectural concepts that differ from older church construction. Its design connects contemporary building practices with respect for regional architectural traditions.

The church is dedicated to the Assumption of Mary and the Hungarian saints. Its gates carry carved motifs taken from the neighbouring 18th-century baroque church, and five crosses above each portal stand for ten centuries of Christian Hungary. The lower level holds a chapel with three frescoes by local painter Márton Árpád.

The church is open for visitors on most days and welcomes people during prayer times. Visitors should wear appropriate clothing and be respectful of ongoing services or ceremonies.

The building was designed under architectural principles that reinterpret regional building traditions in a contemporary way. This blend of modern design with local styles makes it a distinctive example of how religious architecture can evolve in the region.
