Roosevelt Hall, was originally the DeZeng House. The building reputedly was constructed in New York City, dismantled and relocated in Skaneateles.

Samuel Montgomery Roosevelt, cousin of Theodore Roosevelt, bought a 25-room mansion on the shore of Skaneateles Lake in 1899 and renamed it Roosevelt Hall. His cousin visited in 1915 and Franklin Roosevelt visited twice. When Robert Kennedy was running for U.S. Senate in 1964 he considered buying and using the estate as an Upstate home. The deal fell through because the dining room was too small. Mr. and Mrs. Montgomery Roosevelt entertained large house parties over the holidays at Roosevelt Hall in Skaneateles.
