Morris Museum’s Historic Preservation Plan

This fall we embark on the first in a series of preservation initiatives for our eight-acre campus and Twin Oaks Mansion. The Morris Museum was recently designated within the National Register of Historic Places as part of the Normandy Park Historic District. Phase One replaces the original slate roof, repairs the chimneys and dormers, as well as the wood cornice and other exterior features on the 1913 neo-Georgian Revival, brick-clad home originally built for Peter H. Ballantine Frelinghuysen and his wife Adaline (née Havemeyer) using historically accurate processes and materials.

This exhibition brings our visitors into that process, explains the visible construction coming later this year, and shares the importance of preserving this 110-year-old building that the Museum later converted into its main facility in 1964.
