Local Historic Structures

East Islip has roots extending far back into our nation’s colonial period. Summer hotels flourished into the early
1900’s, and residents engaged in boating, farming, shipping and lumbering. During World War II, aircraft and other manufacturing industries provided employment, which stimulated the growth of the building industry and provided homes for the labor force. Today, East Islip is a thriving residential community.

The land that is Islip Terrace today remained largely uninhabited during the early settlement of East Islip. In the late 1800’s, there were just a few scattered farm houses, until Andrew Wolpert Sr. and his sons arrived in 1914. Hoping to build a community where people of German origin could live and work, they were responsible for the large home development which started this community. At that time, the settlement became known as Germantown, until the Post Office was established in December, 1922, and Islip Terrace became the official name.
