The Block House is a historic building located off Naamans Road in Claymont, Delaware. The Block House is believed to be the only structure remaining of original settlement on Naamans Creek.
The Block House was believed to have been constructed in 1654 under instruction of Johan Risingh, who was the last Governor of the Colony of New Sweden. Chief Peminacka of the Minqua tribe had deeded the large tract of land along Naaman’s Creek to John Risingh on behalf of the Swedish colony. The structure was originally designed for defense. During September 1655, the Block House was taken by the Dutch West India Company under Peter Stuyvesant at the same time Dutch forces captured Fort Christina. In 1671, the Block House was attacked by Native Americans. It was captured by the British Army in 1777 during the American Revolutionary War.
Several yards south of the Block House is the Robinson House. The Block House consists of one room with a lower and upper level. Inside is a relatively large fireplace and the former living quarters for the Robinson House cook. The correct date of construction has recently been disputed. Some say the Block House was not built until later, possibly around the time the Robinson House was built in 1723.
