Checkpoint Charlie, the most famous of the inner-German border crossing points and a name known the world over, was where Allied border guards would register members of the American, English and French Armed Forces (and their families) before they visited East Berlin. The "Wall Museum – Museum House at Checkpoint Charlie” is right next to this major tourist spot. The museum displays an incredible number of the original means and tools that people used in their escape out of the GDR: from the hot-air balloon to a mini-submarine, plus plenty of real and fake travel documents.

The Furna is a 100-metre deep tunnel ending in a cave. In the deepest depths you can find a lake with about 130 meters in diameter and a maximum depth of 15 meters.

Whether you decide to take a walk on the river banks or to book a cruise, which you can combine with lunch on board, the Garonne offers plenty of sights for a delightful afternoon or early evening. One company that offers cruising activities in the city is Les Bateaux Toulousains and they have three boats located at Port de la Daurade, Port de l'Embouchure and Port Saint-Sauveur.

Venetian rule in Santorini extended from 1207 to 1580, and the last vestiges of this historical period live in the castles that dot the entire island. Five fortresses can be found in Santorini in Oia, Pyrgos, Emporio, Akrotiri, and Skaros, which have been partly demolished by the earthquakes that shook the island in the 15th and 16th centuries. Skaros is probably the most important and well-preserved among the five castles, built on the peak of the namesake rock to protect the village from pirate attacks. The ruins of the once magnificent fortress can be reached on foot from Agios Georgios church in Imerovigli, connected to Skaros by a 0,5 km walking trail and a long stairway.
