Arch of Galerius and Rotunda, Ancient Roman monument in central Thessaloniki, Greece.
The complex includes a triumphal arch with marble relief panels and a cylindrical rotunda structure featuring a massive brick dome measuring 24.5 meters in diameter.
Emperor Galerius commissioned the construction between 298 and 305 AD to celebrate his victory over the Sassanid Persians at the Battle of Satala.
The Rotunda transformed from a Roman temple to a Christian church and later a mosque, with interior walls containing fragments of Byzantine religious mosaics.
The archaeological site maintains regular visiting hours, and guided tours explain the relief panels depicting military victories and architectural modifications through centuries.
The structure represents the only surviving section of an ancient Roman palace complex in Thessaloniki, with three of its original eight piers remaining intact.
