Get ready to lose yourself (literally!) in one of the world's oldest and largest covered markets, the Grand Bazaar. Construction began in the mid-15th century, and it has grown into a sprawling labyrinth of over 60 streets and thousands of shops. You can find almost anything here: vibrant Turkish carpets, intricate ceramics, dazzling lanterns, leather goods, jewellery, spices, and mountains of Turkish delight. Quality varies, so look carefully. Navigating is part of the fun; note your entry gate or use landmarks. Bargaining (pazarlık) is expected for many items – start lower, be polite, and enjoy the process. It's typically open Monday to Saturday, 09:00 to 19:00, but closed Sundays and holidays.
