The Renaissance Providence Hotel (historically known as the Mason Building, and listed on the National Register of Historic Places under Masonic Temple) — is one of two monumental buildings in central Providence, Rhode Island, USA, that remained unfinished and were then abandoned for decades. Originally intended as a meeting hall for the Freemasons, construction work began in 1927, but was halted in 1929 as a result of the financial crisis of that year. With the outbreak of World War II, construction was halted permanently. It was added (under the name "Masonic Temple") to the National Register of Historic Places in 1993, along with the adjacent Veterans Memorial Auditorium.
