The Arch of Galerius stands on what is now the intersection of Egnatia and Dimitriou Gounari streets. Construction of the arch was spanned the years 298 and 299 AD; it was dedicated in 303 AD to celebrate the victory of the tetrarch Galerius over the Sassanid Persians at the Battle of Satala and the capture[citation needed] of their capital Ctesiphon in 298.[2]
