Lapseki was founded about 500 BC, one of 4 settlements along the Dardanelles at that time. In ancient times, while the city was under the rule of King Mendrom and named Pityausa, the king, who defended the colonists from Foça from the attacks of the local people, minted coins for the first time in its history in the name of his daughter Lapseke and later the city was given this name by the colonists to express their indebtedness to him. In this way, the name Lampsakos, then Lapseki, was passed down to the present day.
