TOP 7 OFFICIAL WORLD LEADER RESIDENCES TOURISTS CAN VISIT

Any tourist going to Washington D.C. should certainly visit the White House. This iconic building can be found at 1600 Pennsylvania Avenue NW in the city of Washington D.C. It is home to the US President, who lives and works there. The White House was built between 1792 and 1800, and designed by James Hoban, an Irish architect. It was built in the Neoclassical style from Aquia Creek sandstone painted white. 
President John Adams was the first President to reside within its walls in 1800 - since then, all US Presidents have. When it was first built, the White House was open for the public to visit, since it was common back in those days for similarly styled country houses in England and Ireland to be open to the public. In 1805, an open house was held by President Thomas Jefferson in celebration of his second inaugural. 

Prague Castle, situated in the Hradčany district of Prague, dates back to the 9th century.

Prague Castle has the special status of being the world's biggest castle from antiquity, a status given by the Guinness Book Records.

The castle, which consists of Romanesque Basilica of St George, Gothic St Vitus Cathedral, a monastery, palaces and defense towers, showcases almost all architecture styles that were used in the last 1000 years.

Fort de Bregnancon is a 17th century fortified castle that is situated on a small island next to the French Mediterranean coast.

In 2013, it was announced it would become open to the public - a move partly owing to the high maintenance costs amounting to around 200,000 euros annually. On June 29 of 2014, the castle received its first tourists, and access can be gained by registering on the Bormes-les-Mimosa tourist department website.
