During the Second Bulgarian State in Veliko Turnovo and the surrounding area, numerous churches and monasteries were built, which became the center of spiritual and cultural life and became a means of self-preservation.

Trapezitsa is the second center of the medieval capital Veliko Tarnovo and was explored archeologically as early as the end of the 19th century, when 17 churches and part of the fortification system of the fort were discovered.

During the Second Bulgarian Kingdom, almost all of the cultural and spiritual life of the Tarnovo throne was centered on the Holy Mountain Hill. One of the largest cultural and cultural centers of the Balkan Peninsula was active here during this era.

The hill has been inhabited since the 3rd millennium BC. In the 5th-7th centuries AD here was the largest city of the Byzantine Empire in the province of Lower Moesia - Zikideva.
