This article attempts to list the oldest buildings in the city of Varna, Bulgaria, including the oldest temples and any other surviving structures. In some instances, buildings listed here were reconstructed numerous times and only fragments of the original buildings have survived. Some dates are approximate and based on architectural studies and historical records. In order to qualify for the list a structure must:

• be a recognisable building (defined as any human-made structure used or intended for supporting or sheltering any use or continuous occupancy);
• incorporate features of building work from the claimed date to at least 1.5 metres (4.9 ft) in height.

This consciously excludes ruins of limited height, roads and statues.
