The 443gallery is a Philadelphia art gallery located in the Roxborough/Manayunk section of Philadelphia. This Philadelphia art gallery is located in the ancestral home of the historic Guggenheim family. Meyer and Barbara Guggenheim raised 8 of their 11 children in this house. Benjamin, their 6th child and father of Peggy Guggenheim, was born in Roxborough in 1865 and died in the sinking of the Titanic in 1912.
