Hartford architect George Keller—who designed the Soldiers & Sailors Memorial Arch in Bushnell Park along with some of the buildings at the Institute of Living—designed the Gallup Memorial Gateway and the Northam Chapel at Cedar Hill, as well as many of its monuments. Cedar Hill has many distinguished architectural features and is listed on the National Register of Historic Places.

There are over two thousand trees of more than one hundred species and varieties, including Weeping Higan Cherry, Huss Hemlock, European Weeping Beech, Shingle Oak, Pignut Hickory, Tanyosho Pine, Cripps Hinoki Cypress and many others.

The public is encouraged to take advantage of self-guided walks using literature available from the office. There are also several programs offered that illuminate the history of Cedar Hill and the notables who reside there, including:
