The Madison Hotel Boardwalk Atlantic City is located in Atlantic City, New Jersey, United States. It was built in 1929 and added to the National Register of Historic Places on December 20, 1984. The 14-story building opened as a luxury hotel at the beginning of the Great Depression in the United States. It went through bankruptcy in the 1960s and later became part of Sands Atlantic City. In 2004, Sands invested $7 million to renovate and reconfigure the property into 126 suites. In 2006, both the Sands and the Madison Hotel were closed.
