The city of Wythburn stood in a narrow valley at the foot of Lauvellen, and at the head of Bracken Water. It was a little but populous village, inhabited chiefly by sheep farmers, whose flocks grazed on the neighboring hills. It contained rather less than a hundred houses, all deep thatched and thick walled. To the north lay the mere, a long and irregular water, which was belted across the middle by an old Roman bridge of bowlders. A bare pack-horse road wound its way on the west, and stretched out of sight to the north and to the south. On this road, about half a mile within the southernmost extremity of Bracken Water, two hillocks met, leaving a natural opening between them and a path that went up to where the city stood. The dalesmen called the cleft between the hillocks the city gates; but why the gates and why the city none could rightly say. Folks had always given them these names. The wiser heads shook gravely as they told you that city should be sarnty, meaning the house by the causeway. The historians of the plain could say no more.
