The ruins of Ahlat, a once-important city for Turkish art and culture, are 44km north of Tatvan county on the western shore of Lake Van and they are today scattered among more recent constructions.
Several mausoleums, notably the Ulu Kümbet, Bayındır Kümbet, Hasan Paşa Kümbet and the Çifte Kümbet, offer a comprehensive overview of Seljuk funerary architecture and decoration.
As you move on and drive around the lake, you will come to Adilcevaz where the Ulu Mosque, built of the region's dark volcanic stone, stands on the lake shore.
