The city of Sapa is mentioned for the first time in an annual of the Holy See of 1062, but it is thought that the city was founded earlier inland of Mount Saint Michael. The city was built in the form of natural terraces and had the typical characteristics of the time with fortifications and surrounding walls, ensuring a safe defense against attacks and constituting what is called the Castle of Sapa. At the end of the 13th century, Helen of Anjou, the queen of Serbia and the archbishop of Tivar, demands the Holy Father to declare Sapa and upper Zadrima a diocese, which is approved in 1291. Only a year later, Sapa will burn totally destroyed by the incursions of the Tartars in the Balkans.
The castle will be rebuilt again at the end of the 15th century and the new diocese will also include the dioceses of Danja and Sarda which were destroyed by the Ottoman occupation in this period. In 1860, the seat of the bishop. was built at the foot of Mount Saint Michael, where it is still located today. At the beginning of the last century, it underwent a total reconstruction.
In 1967, with the atheistic cultural revolution, the bishop building was abandoned and slowly fell into almost total disrepair. Only the front facade with Gothic style architecture is left of it. It features decorative elements and a well-preserved rosette.
