Erechtheion

Worth it if you're into classical architecture and Greek mythology—nearly 30,000 travellers rated it 4.8, which is genuinely strong. The sheer number of guided tours available (145 on Viator alone) means you can find something fitting your pace and budget, though going solo with a decent guidebook works just fine if you're skint. Paid entry stings a bit, but the Caryatids and Porch of Athena Nike are properly iconic and will actually look better in person than your Instagram feed.
