Publisher George Marshall Allen (1863-1941), a pioneer in color printing, built this magnificent 1917 mansion, modeling it after the post-medieval manor house at Compton Wynyates in Warwickshire, England. Prominent New York architect Charles I. Berg designed the house.
Oak paneling 400 years old, taken out of Compton Wynyates during remodeling, adorns the entrance hall. Other parts of the interior were salvaged from English mansions slated for demolition. From 1952 until the 1990s the well-known map making firm General Drafting Company occupied Glynallen. Today it is a private home.
