The Avalon Morningside Park is a luxury apartment building constructed in 2007 on a piece of land that formerly constituted a portion of the cathedral close of the Cathedral of St. John the Divine in the Morningside Heights neighborhood of Manhattan, New York City. The building, a twenty-story glass tower, can be seen from Morningside Park nearby. The Cathedral initially retained ownership of the land, with AvalonBay Communities holding a 99-year lease. In 2019, the land was sold, as well. The diocese explained that it was in desperate need of the $130 million generated by the project, which aroused considerable opposition in the surrounding community.
