Vatopaidi’s main church (katholiko) dates from the10th century. Excavations have unearthed an older basilica, however, from the time of the Byzantine emperor Theodosius the Great (4th century).
Anyone entering the church is transported into a world of the past by the many early Christian architectural and iconographical symbols.
Its architectural style originates mainly from the vision of the three modern founders: Ss. Nicholas, Athanasius and Anthony, three noblemen from Adrianople.
