[2][3] Wallpack Center is located in the Flat Brook Valley 6.7 miles (10.8 km) west of Branchville.

The community, which is located in a rural area, functioned as a service center for the surrounding farms.

In the 1900s, the community declined as larger settlements were able to serve the farms in the region.

[7] The community presently includes the post office, a church, a former school used for storage, and six houses.

It was added to the National Register of Historic Places on July 17, 1980 for its significance in agriculture, architecture, and exploration/settlement.
