Ratac or Ratac Abbey (Italian: Santa Maria de Rotezo, Serbian: Манастир Богородице Ратачке)[1] was a fortified monastic complex on the coast of the peninsula between Bar and Sutomore in modern-day Montenegro.

[3] In the middle of the 15th century people infected with leprosy were treated in this hospital.

In 1407 representatives of the Venetian Republic and Balša III met on the territory in possession of Ratac in attempt to negotiate peace.

[10] In the 15th century the abbot of Ratac monastery was Georgius Pelino, one of the most notable priests and businessmen of his time.

[12] When in the late 16th century jurisdiction of the Benedictine monastery Ratac collapses the Orthodox rite began to strengthen in the area of Catholic parishes Spič, Sozina and Kastel Lastva which were under jurisdiction of this monastery.
