Located on Fifth Avenue in New York, this three-story townhouse was originally built in 1932 by industrialist Howard Stark as his Manhattan residence. It later became the Maria Stark museum, donated by Stark’s son, Tony Stark, through the charitable Maria Stark Foundation. The mansion has now been converted to serve as the home of the Avengers, providing housing, training, and meeting facilities for Avengers members as well as cutting-edge lab facilities and storage for other equipment.
It was primarily looked after by the Stark family AI butler JARVIS who not only takes care of the mansion but also caters to the needs of the Avengers team.
The Mansion has defenses modifed and updated by Tony.
