The Old Daphni Monastery was originally founded and built at the end of the 6th century, to the west of today's Athens. Surrounded by defence mechanisms, the monastery was extended with additional construction over time. The interior holds detailed mosaics and the complex is now a designated UNESCO World Heritage Site, which is worth the little detour by public transport.

The Parthenon and the temple of Athena, is a UNESCO World Heritage Site and the major attraction of Athens. The Erechtheion displays the statues of the female Caryatids, though the original statues have been replaced by copies because of air pollution; the originals are in the new Museum. On the southern slopes of the Acropolis lies the Odeon of Herodes Atticus, a Roman theatre with room for as many as 5,000 spectators. It is used during the annual Athens Festival for world-class ballet and music performances. The Theatre of Dionysus lies beside Herodes Atticus, and almost all the tragedies and comedies of Ancient Greece were written for this theatre.

The Byzantine and Christian Museum in Athens houses more than 25,000 artefacts from the Early Christian, Byzantine and Medieval times. Byzantine culture was almost entirely concerned with religious expression, so in the museum's collection you'll find pictures, scriptures, relief carvings, frescoes, pottery, fabrics and manuscripts.
