Fort Nya Elfsborg

Built in 1643 and named after the Älvsborg Fortress off Gothenburg, Fort Nya Elfsborg was located on the New Jersey side of the Delaware River, between present day Salem and Alloway Creek.

[2] The Dutch established a factorij at Fort Nassau on the east bank of the South River in 1626, and claimed the territory as part of New Netherland.

In 1641, without having a patent, a group of 60 settlers (20 families) from the New Haven Colony (in today's Connecticut) purchased land along the kill and the Schuylkill from indigenous Lenape.

Fort Nya Elfsborg had iron and brass 12pd cannons mounted on earth and wooden palisades.

Log farmsteads similar to those found in Sweden went up around the fort further downriver, so that Dutch West India Company ships coming up from the bay would have to pass them first.
