Twenty steps twist down—

—to a pavement in front of one of the shops in the root of the building.

PICTURE:

Go around the corner to the left and up the street; or turn right along the broad pathway sloping toward the sea; or forge ahead across the street, either waiting for a gap in the traffic or making one. There's no pedestrian crossing here or anywhere on Broad Street, probably because the authorities have given up on choosing any one spot: pedestrians rule, and flow across anywhere they like. (The best system for peopleful streets, as has recently been recognized by making == in London a street without markings.)
