The Westford Knight Memorial Plaque erected in 1976 by Town Historian of Westford, Allister F. MacDougall (1891-1989). The alleged “carving of the Westford Knight” was “discovered” on 30 May 1954 by Frank Glynn (1905-1968)

Prince Henry First Sinclair of Orkney
Born in Scotland made a voyage of discovery
to North America in 1398. After wintering
in Nova Scotia he sailed to Massachusetts
and on an inland Expedition in 1399
to Prospect Hill to view the surrounding
countryside, one of the party died. The
punch-hole armorial effigy which adorns
this ledge is a memorial to this knight
