For a nice walk or picnic a bit outside the busy streets and squares of central Athens, you can head to the Philopappos Hill. It offers a great view over the city and maybe the best view of the Acropolis, just far enough to embrace it all while avoiding the tourists crowd and close enough to see the beauty of its architecture.

St. Mary's Church of Our Lady of Mercy is located on the small island of Prvić and is dedicated to the Merciful Mother. It is known when the works of the monastery started (1461), but it's still unclear when they finished. The monastery was reconstructed many times and completely renovated after the big fire in 1884. If you're planning to pay a visit to the church, know that the island can be reached by ferry from Vodice or from Šibenik.

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 The Erechtheion displays the statues of the female Caryatids, though the original statues have been replaced by copies because of air pollution; the originals are in the new Museum.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.
