The Arch of Galerius and its nearby Rotunda, are ancient monuments built in the early fourth century. The complex to which they belonged was built during the reign of Emperor Galerius (305-311). During its existence, the Rotunda was used as a pagan temple (early fourth century), a church (late fourth century-1590/1912-), a mosque (1590-1912). It is a UNESCO World Heritage Site since 1988.

The church of Panagia Acheroizitis is an extremely well preserved paleochristian basilica. Built in the fifth century on Roman baths, this church was the first to be converted into a mosque around 1430 under the name "Eski Camii" and was used as such until 1930. It is a World Heritage Site. Since 1988

The Hagia Sophia Temple is a rare example of an iconoclastic church (726-787) combining the features of a cross-domed church and a basilica with three naves. Hagia Sophia was built at the turn of the 7th and 8th centuries on a 5th century church destroyed by an earthquake. Converted into a mosque by the Turks in 1523, it remained a place of Islamic worship until 1912 and the return of Thessaloniki into the Greek fold. In 1988, as a paleochristian and Byzantine monument, it was inscribed on the UNESCO World Heritage List.
