Among New Castle’s few surviving early colonial buildings is the elegant brick, early Georgian mansion, the Amstel House. Built in the 1730s by the town’s wealthiest landowner, Dr. John Finney, the house is graced with original woodwork, fine architectural details and open hearth. Its early fanlight and central hallway were among the first uses of these features in the town. Walk-in, guided tours are available Apr. 1 - Dec. 31.
