The northeastern round tower on "Iskar" Street is part of the Historical and Archaeological Reserve "Ancient Serdika - Medieval Sredets".
It is located in the sector, where the eastern and northern fortress walls meet at an angle and belongs to the earliest fortification belt of the city.It was built in several stages.
Conservation of the site was carried out at the end of the 1950s.
The work of the Regional History Museum - Sofia is focused on the emergency conservation of the authentic remains. Constructional problems were found after extensive expert studies and analyzes (eroded solution, compromised original building material), which have led to deformations of the original walls (landslides, cracks, destruction of walls). The emergency conservation and restoration works aim to protect the original substructure from harmful atmospheric influences.
The activities related to the emergency conservation of the archaeological site are carried out by a contractor firm, which has the necessary permit.
The northeastern round tower is an artefact with a high degree of material and visual authenticity and the Regional Museum of History - Sofia, guided by respect to the original, seeks to preserve the immovable cultural heritage for citizens and visitors of Sofia.
