Fort Beversreede (after 1633–1651) was a Dutch-built palisaded factorij located near the confluence of the Schuylkill River and the Delaware River. It was an outpost of the colony of New Netherland, which was centered around its capital, New Amsterdam (Manhattan), on the North River (Hudson River).
The exact location of the fort is uncertain. A 1655 Swedish map shows it on the west bank of the Schuylkill River, on Providence Island (now part of the mainland), just south of Minquas (also known as Eagle's Nest or Mingo) Creek. Scharf & Westcott put it on the east bank of the Schuylkill River, opposite Minquas Creek. A 1770s map of Philadelphia's naval defenses shows a fort on the island, but it is unidentified.
Directly adjacent to (or opposite) the fort was the terminus of the Great Minquas Path, an 80-mile (130 km) trail from the Susquehanna River to the Schuylkill River. This was the primary trade route for furs from the Susquehannock people, and the Dutch named the trail "Beversreede" or "Beaver Road."
Though never recognized by the Dutch, the Delaware Valley region was effectively under control of the Swedish colony of New Sweden, which was first settled in 1638 at Fort Christina (now Wilmington, Delaware). Though the Swedes' colony included Dutch residents, the only official Dutch presence in the area was across the Delaware River at Fort Nassau, at the mouth of Big Timber Creek (south of today's Gloucester City, New Jersey). In 1642, members of the Connecticut Colony attempted to settle in the area, but their homes were burned and the nascent colony was repelled.
The Swedes had a competing claim for land at the mouth of the Schuylkill River, and they often vandalized Fort Beversreede. In 1648, they built a stockaded 30-by-20-foot blockhouse directly in front of it. Their Fort Nya Korsholm was meant to intimidate the Dutch residents and intercept trade. In 1651, the Dutch abandoned Fort Beversreede and dismantled and relocated Fort Nassau to the Christina River, downstream from the Swedes' Fort Christina. The Dutch consolidated their forces at the rebuilt fort, renamed Fort Casimir. It was not until 1655 that control of the area was regained by the Dutch in a military expedition led by Director-General of New Netherland Petrus Stuyvesant, establishing a regional capital at New Amstel.
There is no remnant of either Fort Beversreede or Fort Nya Korsholm. Nearby Mud Island became the site of Fort Mifflin in 1771. Widening of the Schuylkill's channel, subsequent land reclamation, as well as other transportation and industrial infrastructure have dramatically changed the area. But the site of the forts (whether on the east or west bank of the Schuylkill) is probably south of the mouth of Mingo Creek and north of the George C. Platt Bridge.
