Topkapı Palace

Topkapı Palace was the center of Ottoman power from the 1460s until the mid-19th century. Walking through its series of courtyards, you move from the public administrative areas into the increasingly private realms of the sultan and his court. It's less a single building and more a collection of kiosks, halls, and treasuries set in gardens, housing everything from imperial robes and weaponry to religious relics. The scale is immense, and the views over the Golden Horn, Bosphorus, and Sea of Marmara from the terraces are a key part of the experience. Give yourself time to wander; the real feel of the place comes from the courtyards and the sense of history in the quiet corners, not just from peering into display cases. The Harem requires a separate ticket but is worth it to see the intricate tilework and understand the private world of the palace.
