Paris, world capital of art and culture, gathers some of the most famous museums and monuments in the world.

Sights that should not be missed include: The Louvre and the Musee d'Orsay. Visit any of the many others according to your tastes and interests: the Musee Picasso, Musee Rodin, Musee Carnavalet, Musee Marmottan and the Arab Institute are just a few. Essential Paris monuments are the Eiffel Tower, Notre-Dame cathedral, the Arc de Triomphe or the Grande Arche de la Defense.

London is undoubtedly one of the world's finest cities. In addition to numerous monuments from its more glorious past, London is equally well-known for its pageantry and tradition. London has something for everyone - wide boulevards buzzing with excitement far into the night, quiet squares and explorable alleyways. Visit this famous city's parks, museums, galleries, monuments, abbeys and churches, skyscrapers and ruins, Georgian squares. Take in such events as the Ceremony of the Keys at the Tower, or the Changing of the Guard at Buckingham Palace, or even one of the many theatrical productions. Some of the most exclusive shops are found along Oxford, Bond and Regent Streets. An old favorite and one of the world's premier institutions is Harrods - offering everything from Chanel suits and sliced salmon to caviar and even pets.
