The Basilica Cistern was again renovated and restored by the municipality between 2017-2022.
The most recent restoration aimed at improving the seismic safety of the cistern (by installing tension bars between the arches and columns). The heavy platform was renewed as well in the form of a light steel one. The removal of cement imitation from the floor tiles also revealed brick stamps from the 5th century. A new entrance and exit was also added to the Cistern by the museum.
