The New Castle Historical Society's three museums—the late-17th-century Dutch House, the 1730s Amstel House, and the 1892 Old Library Museum—tell unique stories about the town's past and its residents. From Dutch laborers and British colonial governors to prominent American architects, the New Castle Historical Society celebrates New Castle's diverse history from the town's 17th-century founding through the preservation efforts of the 21st century. The Society offer tours, educational programs, and recreational and educational events.

Student museum tours are available that emphasize colonial and revolutionary Delaware and American history. Ideal for fourth and fifth grade students, our tours are aligned with Delaware history education standards. Additional tours are available for other grade levels.

The Society’s website offers an events calendar, visitor information, and an online gift shop.
