 In 1795 , François Alexandre Frédéric visited Spanish Hill while en route to Canada . He described the hill as " a mountain in the shape of a sugar loaf , about 100 feet high , with level top , on which are remains of <unk> . One perpendicular <unk> is still remaining , plainly indicating a parapet and ditch . " In 1833 , another individual visiting the hill described " the remains of a wall which runs around the whole exactly on the brow , and within a deep ditch or <unk> running round the whole summit . " In 1898 , <unk> Shepard created a sketch of Spanish Hill , including the portions still visible at the time as well as those no longer extant . Shepard enlisted the assistance of a longtime local resident , Charles Henry Shepard , who claimed to remember " fortifications as consisting of an embankment with a trench behind , giving a height of four or five feet on the inside . " In addition , an <unk> was discovered on the site which was pronounced to be a corn <unk> by <unk> .
