When walking down the Rue du Gros Horloge you will, soon enough, come across the splendid “Gros Horloge” itself. This beautiful clock is one of the most famous landmarks of Rouen, and likely the oldest mechanism of its intricate kind still in existence. You can go up the belfry and enjoy a cup of coffee in a café below right after.

Maintained by the Sandusky Library, the Follett House Museum, itself listed on the National Register of Historical Landmarks, features an array of artifacts and exhibits that chronicle the history of Sandusky from its very beginnings. Included is the prison camp memorial.

The National Archaeological Museum, in Exarchia, is home to Ancient Greece’s most spectacular pieces. One room contains Schliemann’s finds from Mycenae, another has the famous frescoes from Santorini on display. There is also a fine collection of idols from the Cyclades and ceramics from all parts of the Mediterranean. The star of the museum is the Antikythera Mechanism, an ancient hand-powered orrery, described as the oldest example of an analogue computer used to predict astronomical positions and eclipses decades in advance. This scientific marvel is dated somewhere between 205 and 60 BCE.
