Louvre museum was originally built as a 12th century fortress, then converted into royal palace in the 14th century, and then became a public museum at the end of 18th century. It is now one of the largest and most visited museums in the world. The museum contains the collections of antiquity, European paintings and sculptures, and other Roman, Egyptian , Greek and oriental work of arts. The most famous collection in the museum is the Leonardo da Vinci's Monalisa painting. The most recent addition to the Louvre was the construction of the glass pyramid in 1989 which functions as the museum's main entrance. The design of the glass allows the sunlight to come in on the underground floor. (Paris, France / 2010)
