Cheapside, Cross and Conduit, 1638, (1809). The procession of Marie de Medici along Cheapside in the City of London, part of the French Queen's visit to King Charles I and her daughter Henrietta Maria. Here her entourage passes the Cross (centre) and the Conduit (seen on the right). The Cheapside Cross was one of the Eleanor crosses, a series of twelve stone monuments topped with tall crosses, erected between 1291 and 1294 by King Edward I in memory of his wife Eleanor of Castile. The Great Conduit was a man-made underground channel which brought drinking water from the Tyburn to the City. On Cheapside there was a building where citizens could draw water.
