Fort Thunder was a warehouse on the second floor of a pre-Civil War former textile factory in the Olneyville district of Providence, Rhode Island. The space was used from 1995 through 2001 as a venue for underground music and events. It was known for its colorful posters promoting these shows posted on walls around Providence. At various times they hosted costumed wrestling and halloween mazes. Several artists lived and worked there; this group of artists is also sometimes referred to as "Fort Thunder."
