About The Chelsea Mansion
The Chelsea Mansion is the former home of Alexandra and Benjamin Moore, located on the 550-acre Muttontown Preserve. Built in 1924, Chelsea Mansion was a dream, inspired by a yearlong international honeymoon. This grand historic mansion, designed by William Delano (of the architectural firm of Delano & Aldrich) can provide a timeless and classical setting for gatherings of all types and sizes.
CAPACITY: 25–250 guests
