The Prudential Center is a mixed-use complex of four office buildings in the Back Bay neighborhood of Boston. It originated with the Prudential Tower in 1964, and was followed by 101 Huntington Avenue in 1973. The shopping mall concourse level that connects the towers and surrounding buildings opened in 1993. 111 Huntington Avenue and 888 Boylston Street were connected to the concourse upon their 2001 and 2016 openings, respectively. It connects to several nearby destinations managed separately from the center including the Copley Place shopping mall, the Hynes Convention Center, the Sheraton Boston Hotel, and Prudential station serving the Green Line E branch of the MBTA subway.
