Bowman's Castle, also known as Nemacolin Castle, was built in present-day Brownsville, Pennsylvania, at the western terminus of the Nemacolin's Trail on the east bank of the Monongahela river. It was built around the original trading post, which was built near the site of Fort Burd, the latter built by British colonists during the French and Indian War. Construction on the castle, including addition of a crenellated tower, continued through the Victorian era, when it was considered an engineering marvel.HistoryThe trading post was built shortly after the American Revolutionary War, in the mid-to-latter 1780s. Jacob Bowman began constructing the castle during the mid-to-late 1790s in the community once known as Redstone. The trading post was located at the Redstone Creek river crossing. The community built flatboats for travelers and traders on the Ohio and Mississippi rivers. It was the long-time terminus of the western part of Nemacolin's Trail.Likely more than 1,200 years before construction of the fort, trading post or castle, prehistoric indigenous peoples had also found this site a strategic one. They built the earthwork mounds which the colonists called Redstone Old Fort. Fort Burd was built on top of its sandstone base.
