On one of the peripheral hills towards Zvezdara, close to Crveni krst, between the Bregalnička and Pop Stojanova Street, stands a very unusual church in Belgrade.

The follower of Francis of Assisi and a great preacher, one of the most respected western Christian saints, originating from Lisbon, where he lived by the end of the twelfth and in the first half of the thirteenth century, rests in Italian town Padua.

The building has the basic form of rotunda, with an apse in the east, the porch in the west and cylindrical bell tower in the southeast side; it was not built according to the initial, but to the second, slightly altered project of the architect Plečnik.

The main room is circular and cylindrical, 25 m in diameter and 17.5 m in height, with side conches, that is, the horseshoe shaped chapels in the thickness of the walls of rotunda, which are intended for special small altars and the confessional.

Three conches are arranged on both north and south side, whereas opposite the entrance, in the apse, there is the main altar, that is, a deep presbytery, under which there is a crypt.

The main altar of the St. Anthony is in the apse, with the bronze sculpture of the patron of the church holding the infant Jesus Christ, the work of Ivan Meštrović, set in 1935.

It is one of the rare examples among the rest of the churches of this catholic order, of mostly basilica forms, due to the type of the central building.
