On the picture (from left to right):
The Yıldız Hamamı (Turkish bath) and the Hatuniye mosque, both built in 1510; the Hazeranlar Konağı, a large 19th century mansion that is now an ethnographical museum.
In the background: Five royal Pontic rock tombs (3th-2nd century BC) and some walls of Kızlar Sarayı, the partly restored fortified palace of the Pontic kings, which was transformed into a (lower) fortress/residence by Romans, Byzantines and Turks.
On top of the rock: the medieval Amasya Castle (also called ‘Harşena Castle’), some 300 m above the river. The first real fortress there dates probably from the time of the Pontus king Mithridates I (around 280 BC). It was expanded and repaired by the Romans, the Byzantines and the Ottomans.
