The "Birth of Saint John the Baptist" Orthodox Cathedral is a monument of baroque architecture, located in Arad. The edifice was built between 1862-1865 under the direction of a local architect named Anton Ziegler.
After the former church had been demolished, bishop Procopius Ivaşcovici (1853-1873) initiated the construction of a representative sanctuary in the so-called “Tekelija Garden”. The design belonged to architect Anton Ziegler.
The works took place between 1862-1865. The facade of the church is worked in classical Baroque style and finished with a triangular tympanon. In 1966, the main façade was decorated with three beautiful mosaics.
The bell dating from 1764 was brought from the old demolished church. In the buildings annexed to the Church, the Orthodox Theology Seminar functioned for a while, whereas today, they house some of the offices of the Diocese.
