Atatürk's Birthplace is a pink Ottoman house in the Turkish consulate grounds near the waterfront, open to visitors as a small museum. Turkey maintains the property under a long-standing arrangement, and entry is free. The house has been furnished to suggest early-20th-century bourgeois Ottoman life, with period furniture, photographs, and personal effects. It is modest in scale but the story it embodies is enormous.
The visit works best if you know something about Atatürk before you arrive. The great irony of the place — the founder of modern Turkey's secular nationalism born in a cosmopolitan, multiethnic Ottoman city that would become purely Greek within a generation — is one of the key threads running through the 20th century history of this whole region.
