With over 100 galleries from around the world, the Detroit Institute of Art boasts the US's fifth-largest collection of art. It houses work by Diego Rivera, Van Gogh and Henry Fuselli as well as an extensive collection of African-American artwork.

Born from an idea of Henry Ford II, this group of seven interconnected skyscrapers was intended to boost Detroit's economy. The central tower is the tallest and certainly the most iconic building in Detroit which, with its majestic figure, offers an ideal observation point. This modernistic construction houses the General Motors and it is doubtlessly worth the visit.

On the left hand side of the port you can find the Lighthouse Palace, a congress and conference building ideally located in a park with great views of the water and islands. Heralded as one of Marseille's most beautiful palaces, "Palais du Pharo" was first constructed for Napoleon III in 1858.

Constructed around the Church of the Holy Sepulchre, in the north-western part of the Old City, the area is home to several Christian sights. Few houses can be found here — it's mostly about religious buildings, educational facilities, and a plethora of cafés, restaurants, and shops. The streets are packed with vendors. It is especially worth exploring the area of Mauristan, teeming with shops and colourful stalls. Used as a market during the Roman Empire, the area hosted churches and hospices during the Crusades (in Persian, "Mauristan" means hospital).
