Co-cathedral of Christ the King in Belgrade, Catholic co-cathedral in Vračar, Belgrade, Serbia

The Co-cathedral of Christ the King is a three-nave basilica featuring Romanesque Revival design, with Corinthian columns and decorative mosaics adorning its brick facade. The structure stands out for its distinctive arched windows and detailed ornamentation throughout.

The parish dates to 1888, when a chapel of St. Ladislaus was built in the courtyard of today's church. Construction of the new church began in 1924, and it was consecrated that year by Apostolic Nuncio Pellegrinetti as cathedral of the newly established Archdiocese of Belgrade. It was enlarged to its present size in 1926 and dedicated to Christ the King in 1927. Since 1988, when the new Cathedral of the Blessed Virgin Mary was consecrated, it has held the title of co-cathedral.

The church is dedicated to Christ the King, a feast first celebrated on 31 October 1926, the day the expanded church was consecrated. Since 1988 it has served as co-cathedral and is now used mainly for diplomatic meetings, requiem Masses and interreligious gatherings. The mosaic above the entrance shows Christ Blessing.

The church stands at Krunska 23 in Vračar, behind a small churchyard enclosed by a wrought-iron gate; the rectory is to its right and the bell tower to its left. Since 1988 it has mainly hosted diplomatic meetings, requiem Masses and interreligious gatherings rather than regular parish worship, so check the current schedule before visiting.

The pipe organ in the choir loft was built in 1927 by Franc Jenko, with 14 stops on two keyboards and a pedal keyboard. The Serbian sources call it the first organ in Serbia, played for the first time on 15 December 1927 and still in use.
