Long Pond Ironworks was founded in 1766 by German ironmaster Peter Hasenclever. Hasenclever brought 500 ironworkers and their families from Germany to build an ironworks "plantation," including a furnace, forge, houses, shops, and farms. A dam at "Long Pond" (Greenwood Lake) on the upper Wanaque River provided the hydropower to operate a blast for the furnace and a large forge. Two more furnaces were constructed in the 1860s. Operations at the site ceased in 1882 due to the industry-wide conversion to anthracite furnaces using Pennsylvania coal. The remnants of the ironmaking industrial structures at this site date from the 18th and 19th centuries. Furnaces, casting house ruins, charging areas, ice houses, waterwheels, and other structures are a part of the remains. The area is currently undergoing restoration: one waterwheel has been reconstructed and several houses stabilized. The "Old Country Store" has been renovated and now houses the Long Pond Ironworks Museum. The original Village of Hewitt grew up around the 19th-century iron enterprise. This settlement included a church, a store/post office, schoolhouses, and dwellings and outbuildings for workers and managers. Many of these cultural resources remain intact or as ruins.

The Seabrook Schoolhouse was built in 1896 by the residents of the Seabrook community and provided education for grades one through eight until the early 1950s. This one-room schoolhouse is one of the few surviving one-room schoolhouses in Prince George's County. The building is unique in that it was built to resemble the Victorian Gothic architectural style of the cottages that were originally built in the community. The schoolhouse has been restored and continues its legacy of education. It is open for tours by appointment and features a multifaceted, overall program that includes interpretive exhibits and artifacts and programs.

Visitors to the Astor House Museum and Clear Creek History Park can explore how the people of Golden, CO, settled a bustling town that served the developing West as a government center and mining supply town. They can tour an 1800s boarding house and homestead where early Colorado pioneers worked and played, see what life was like on the frontier, and hear stories of the people who called this place home. The Astor House was built in 1867 and stayed in continuous operation as a boarding and rooming house until 1971—over 100 years! It rented rooms and served hot meals to lawmakers, laborers, miners, students, and families, some of whom stayed for weeks or even months.
