East and west through the county of Surrey runs the chalk ridge of the North Downs, the great highway of Southern England from the Straits of Dover to Salisbury Plain. Of all English roads, it has carried the longest pageant. It saw the beginnings of English history; for four centuries it was one of the best known highways in Christendom: the vision from its windy heights is one of the widest and most gracious of all visions of woods and fields and hills. By the trackway they made upon the ridge came the worshippers to Stonehenge; Phoenician traders brought bronze to barter for British tin, and the tin was carried in ingots from Devon and Cornwall along the highway to the port of Thanet; Greeks and Gauls came for lead and tin and furs, and the merchants rode by the great Way to bring them. When Caesar swept through Surrey on his second landing, his legions marched over the Way before he turned north to the Thames. When the Conqueror drove fire and sword through Southern England, he went down to Winchester by the chalk ridge; and when the great lords under the Conqueror and Rufus, Richard de Tonebrige and William de Warenne, built their rival castles, they built them to command the highway; so did Henry of Blois build his castle at Farnham; and so was Guildford Castle built. Of warfare later than Norman days, the Way saw nearly all that went through Surrey. Simon de Montfort and his barons rode fast by the ridge the year before Lewes; they lay at Reading on the twenty-ninth of June, and on the first of July at Reigate. In the wars of the Parliament, Farnham west of the Way saw the siege of an hour; Lord Holland led his little band from Dorking to Reigate and fled back again. Last of the echoes of Stuart battles, Monmouth, after Sedgmoor, was driven through Farnham to lodge for one night of misery and fear at Abbot's Hospital in Guildford. But the Way has another meaning and other memories. It is as the Pilgrims' Way that it is best known, and as the Pilgrims' Way that it has been written about and tracked and traced and surrounded with legend and story and the haunting melancholy of an old road once used and now half forgotten. The Pilgrims' Way is more than the old Way, for it runs by more than one road. The old Way took its followers along the ridge or just under it, high in the sun and wind where the traders and fighters could see their route clear above the thick woods of the Weald. The Pilgrims' Way lies as often on the low ground as on the hill. But it follows the line of the chalk ridge, and the parallel roads, though here and there it would be difficult to choose between them as to which was most used by travellers, have become vaguely named the Pilgrims' Way, and as the Pilgrims' Way they remain.
