About Calvert Vaux Preservation Alliance

Calvert Vaux Preservation Alliance (CVPA) works to restore and find sustainable uses for the Vaux-designed Hoyt House and landscape at The Point in Staatsburg, NY, as well as the site’s 20th-century barn complex and gentleman’s farm. We work to expand awareness of the pivotal role played by Vaux in American architecture and landscape design, and to make The Point a place where his work can be experienced and enjoyed. A 501(c)(3) nonprofit organization, CVPA serves the Mid Hudson economy by developing sustainable uses for The Point’s many structures, drawing visitors to Mills Norrie Park, and creating greater appreciation for the many exciting Vaux resources throughout the region. We serve all Americans by helping to forge a more complete narrative of our nation’s cultural history.
