Palace of Galerius

A 14th-century chapel.

A church from the 7th century, based on the Hagia Sophia in Constantinople, with mosaics from the 9th century.

A church built in the 14th century. Few of the building's original wall paintings survive, but its architecture is striking.

A 34 m fortified tower from the 16th-century, the primary symbol of the city. It was part of the city's erstwhilse Byzantine walls, and became a prison under the Ottomans. Today it houses a small museum dedicated to the history of the city, and viewpoints at the top. The exhibits are only in Greek, but the museum provides WiFi and an MP3-based audioguide.

Started life as a Roman temple of Zeus, built by Caesar Galerius, and is almost as old as the Pantheon in Rome. The monument has a diameter of 24.5 m and its dome reaches a height of 30 m. It was converted into a Christian church during the Early Christian era, and its interior was decorated with magnificent mosaics. However some inside frescoes are a work of the British artist Alexander Rossi (1840-1916). In 1591 the Rotunda was converted into a mosque, and a tall minaret still stands beside the monument. Frequent earthquakes from the early 7ᵗʰ century until 1978 caused several damage. The latter caused the destruction of the dome section. After being restored, the monument reopened to the public in 1998.
