Amstel House, also known as Dr. Finney House, is a preserved building in New Castle, Delaware, USA. 19th century New Castle's decline 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.
