The National Museum of Colombia (Museo Nacional de Colombia) is one of many national museums with "clear bones". The museum's predecessor turned out to be a prison, in the shape of a cross, which still retains the original appearance of the time. The museum has a collection of nearly 20,000 archaeological artifacts and artworks, introducing the historical changes of Colombia from the former Columbus period to the middle of the last century. The most famous is the "multiple walls", which combine modern technology with various murals, like the moving paintings in Hogwarts Castle. In so many art works, feel the happiness of being an "art prisoner" in detail.
