What it's like
The Galerian Complex is the palace built by Caesar Galerius. Construction began at the end of the 3rd and the start of the 4th century AD. Its ruins now form an open-air museum in the heart of the modern city, and the site was honored by the European Union and Europa Nostra in 2008 for its restoration.
A visit is a short walk through the city center. The Arch of Galerius stands on Egnatia and Dimitriou Gounari streets and is free to see. Some remains, such as the Apsidal Hall, are open to visitors, while most of the rest lies buried beneath the streets around it.
Good to know
- The arch is free to visit at any time you pass by on Egnatia Street.
- There is an information center for the Galerian complex on the site.
- Most Galerian remains are buried under the historic center and cannot be seen.
