The Koza Han is a beautifully preserved Ottoman caravanserai built in 1491 by Sultan Bayezid II, sitting in the heart of Bursa's old bazaar district beside the Grand Mosque. Two storeys of arcaded rooms surround a courtyard with a small octagonal fountain mosque (mescit) in the centre, and a mulberry tree that has been growing here for centuries. The whole thing has been carefully maintained and is still in use as a commercial centre.
Today the ground-floor shops and upper galleries sell silk products — scarves, ties, handmade textiles — along with jewellery and handicrafts. Prices are negotiable. This is a good place to buy quality silk goods; insist on seeing the certificate of origin if you want to know the fibre is genuinely local. The adjacent Bedesten (covered market) and Sipahilar Bazaar extend the warren of covered shopping for another few blocks in both directions.
