This han (a caravanserai) was constructed in 1572 and is an excellently preserved example of the architecture of that period.
Hans were used as accommodation and storage places for merchants as they passed through town, often including stabling facilities for their horses (or camels) and sometimes recreation facilities such as restaurants and hamams (Turkish baths) as well.
The Büyük Han has been painstakingly restored to its former glory, with the former sleeping quarters now home to a variety of shops, cafés, and local artisan ateliers, perfect for a spot of shopping to break up your old city sightseeing.
