A rather new museum with a modern museography and well made that gives a very good idea of the ancient city of Nicopolis. The progression is chronological.
The ticket price of the archaeological site allows access to the museum. It is essential to do both, in my opinion first the site then the museum. Small museum but not many people so it's a very nice visit. The museum is not directly next to the site (itself erupted in different places) but 2 km to the city of Preveza.
