This remote but important city is settled in a verdant oasis at the foot of a rocky peak. An imposing ninth century BC citadel overlooks the new and old parts of the town. Steps carved in the rock lead to the Urartian fortress and halfway up inscriptions in cuneiform pay homage to Xerxes. Inside of the fortress are several Urartian royal rock tombs. In the old city the Ulu Mosque, Hüsrev Paşa Mosque, Kaya Çelebi Mosque and the İkiz Kümbet (Twin Mausoleums) reflect the Seljuk and Ottoman architectural styles. Still very much part of a traditional lifestyle, the women of Van produce beautiful kilims (rugs) woven in blue, red and white patterns. The exotic Van cat that is a symbol of the city has thick white fur and eyes of one colour eachblue and green. The philatelic sections of major Turkish post offices have beautiful Van cat stamps for sale.
