Concierge.com's insider take:
The National Archaeological Museum is newly (post-Olympics) renovated and a must-see. With 48 rooms, it's the largest museum in the land, but still way too small for everything to be on display—especially since 30,000 further objects of antiquity were unearthed during the Metro construction. See rooms and rooms of sculptures from 700 B.C. to the early Byzantine era, including (no surprise) the world's most important collection of ancient Greek works, and don't miss the curiously haunting 14th-century B.C. golden Mask of Agamemnon.
