The Nativity Church is the oldest church in Arbanassi. Originally built during the 15th century the simple low level building belies the wealth of art to be found within. Nearly every inch of the vaulted interior is covered in paintings and frescoes dating back to the 17th century. Scenes are from the old and new testaments: the life of Christ, the virtues of the Virgin Mary, there is even a frieze of Greek philosophers and several inscriptions of the benefactors and sponsors. The 'Wheel of Life' on the east wall of the north gallery is the earliest depiction of this type in Bulgarian churches.
