Hersekzade Ahmet Pasha Mosque
The mosque, which is located between Karamürsel and Yalova on the shores of the Gulf of İzmit and is actually part of a small social complex, was built by Hersekzâde Ahmed Paşa, one of the grand viziers of the reigns of Bayezid II and Selim I. Its foundation charter, which was approved in Ramadan 917 (December 1511), is in the John Frederick Lewis collection at the Philadelphia Freer Library in America. There is no information about the mosque, whose exact date of construction cannot be determined, in contemporary sources. However, Evliya Çelebi reports that the town of Hersek, which he visited in Şaban 1058 (September 1648), was founded as a settlement of 700 households with the goods of Ahmed Paşa’s jihad.
