Cross-section sketch of proposed wall intended to prevent the English and Indigenous peoples from invading the Dutch colony of New Amsterdam. The sketch depicts an embankment and a ditch. The line projecting from the top of the wall may be a fraise, small sharp sticks to impede scaling the wall. The Dutch reads: “9 feet above ground, 3 feet in ground.” One dot = one foot. This design was never carried out due to cost. Court Minutes of New Amsterdam, New Amsterdam records, NYC Municipal Archives.
