Crown Point iron was an indispensable product for the North in the Civil, War. Iron from Crown Point was used to construct the battleship Monitor.
The museum contains samples of iron ore mined by Penfield, along with pictures of the mines in operation.
Rooms in the museum are furnished with original pieces once belonging to the Penfields. Other historic furniture is also on display.
Ironville was placed on the National Register of Historic Places in 1974. The homes along the main street were all constructed in the early 19th Century.
Those buildings, besides the museum, include the Harwood House, a church, a parsonage, a boarding house, and homes, and barns that have been in use for 150 years and longer.
There are 10 stations along a self-guided tour. Year-round historical and recreational trails wander across the 500 acres of the homestead.
In the summer, hiking and camping are available near the Penfield Pond.
