De Vries Palisade, also known as DeVries Palisade of 1631, is an archaeological site located at Lewes, Sussex County, Delaware. It is the site of the Zwaanendael Colony, the first permanent European presence on the Delaware Bay in 1631, settled by a group of settlers under David Pietersz. de Vries. The settlers landed near this spot to form a whale hunting station and agricultural settlement. A monument was erected on the site; it was dedicated on September 22, 1909.[2]
