An Arch will be Built over an Ancient Tomb in front of the Sofia Town Hall – Telegraf newspaper, Oct 19, 2018.2018

The artefact remains closed, its scriptures will be recreated on top of it. 

The ancient tomb from the early Christian period (5^th-6^th c. A.D.) has been uncovered this summer during renovation works at Moskovskastreet, right across from the Sofia Town Hall. This is yet another tomb from the East-side necropolis of the ancient town of Serdika. Inside the tomb there are impressive bright-colored murals depicting two crosses as well as floral motives. Mr. Peev, dipl. Architect and CEO of EKSA, presented the design for preserving and exhibiting the tomb. The murals will be recreated and shown for the public at the ground level. The pavement of the sidewalk right above the tomb will be painted in a different color and its shape will resemble that of the tomb underneath. There will also be an arch built on top, with a color appropriately corresponding to the hues of the bricks of Saint Sofia church, located right next to the tomb.
