Excavations in the New Palace Yard at the Palace of Westminster, between 1972–4, have illuminated the development of this historic site on the northern periphery of the medieval palace. The Yard was first laid out in the late thirteenth or early fourteenth century over previously marshy land at the edge of Thorney Island. In the central area of the Yard, part of the foundation of a magnificent fountain, known historically as the Great Conduit was found. Built in the mid-fifteenth century, the conduit formed a major landmark until its demolition some two hundred years later. Preserved within its foundation were the fragmentary redeposited remains of a high quality fountain of polished Purbeck marble, dated to the late twelfth century. Due to the enormous scale of the building works significant environmental evidence was recovered allowing elucidation of the topographical development of this important site, from the prehistoric period to the creation of the Yard in the late thirteenth century.
