New Castle Presbyterian Church is a Presbyterian Church (USA) congregation located in New Castle, Delaware which conducts worship services weekly within a historic meeting house, which was erected in 1707. It was founded as a Dutch Reformed Church in 1657 because a clergyman of that faith had accompanied Peter Stuyvesant when building Fort Casimir in 1651. The founding date of the congregation was marked by the arrival of the first permanent pastor for the congregation, Reverend Evardus Welius on August 21, 1657. By 1664, the British had taken control of the colony from the Dutch, leading to an increase in French Huguenot, English, and Scottish colonists taking residence within the town. Upon the arrival of Rev. John Wilson, as Scotsman, the church took on its distinctive Presbyterian form. Francis Makemie, Rev. John Wilson, and six other ministers met within Philadelphia in 1706 to organize the first Presbytery in the New World.

Amstel House, also known as Dr. Finney House, is a preserved building in New Castle, Delaware, United States, built in the 1730s. The decline of New Castle in the 19th century meant that many owners of homes could no longer afford to make changes to them, which is why so many buildings were preserved. That changed, however, when New Castle was "rediscovered" during the Colonial Revival phase of the 1920s and 1930s and old buildings began to be torn down and replaced by new construction.In 1931, to protect New Castle's heritage, a group of concerned citizens raised funds to buy the Amstel House, which faced an uncertain fate. This was the town's first formal preservation effort. Shortly thereafter the group evolved into the New Castle Historical Society which, in the 75 years that have followed, has worked closely with the city and other civic organizations to save, preserve and restore many of the town's historic architectural treasures. It was listed on the National Register of Historic Places in 1977.
