Museum Mile is the name for a section of Fifth Avenue running from 82nd to 110th streets on the Upper East Side, in an area sometimes called Upper Carnegie Hill. The Mile, which contains one of the densest displays of culture in the world, is actually three blocks longer than one mile (1.6 km). Nine museums occupy the length of this section of Fifth Avenue. A ninth museum, the Museum for African Art, joined the ensemble in 2009; its museum at 110th Street, the first new museum constructed on the Mile since the Guggenheim in 1959, opened in late 2012.
