The sector of the double fortress wall along Vitosha Street is one of the few places where the fortifications are visible above the surface during the years to our time. The first wall from the period II-IVc today can be traced to the foundations of several buildings. Several of its sectors have been researched in connection with the reconstruction of buildings and the conservation of the wall. The second fortress wall is partially preserved. The outer fortress wall (Early Byzantine) was built in V-VI c. The double fortress wall visible at Vitosha Street is exposed at a height of about 1m. The building is in opus mixtum with brick belts of 5 rows of bricks, welded with more brick pieces. During the development of the sector several times in the 20th century a part of the supporting structure of the wall was revealed. The building in the blocks of syenite in a row of masonry and filling inside of a brick block block with a bundle of bricks. The next brick zone is partially preserved. Triangular towers and counterparts are built to the wall. The towers are in the form of an isosceles triangle with a length of 7,80 m and a wall thickness of 1,55 m. They stand 34 m apart. Between the two triangular towers lie the remains of two counter-attacks. They are 16 m apart and are projected at 1.7 m from the outer face of the wall.
