_Streets._—In his account of the Bucklersbury pavement, Price describes also some walls which were found “about 30 yds. westerly from the pavement” (the position is shown on his plan). “Two Roman walls running nearly in line with Bucklersbury directly towards the Walbrook.” In the space between them had been laid a drain to fall towards the brook with a tile pavement above, and mortar fillets against the walls. The walls were 2¾ ft. thick, and built on three rows of piles, and the space between was 2¼ ft. The tiles are of the usual kind of red and yellow brick. Above these walls were others of chalk and stone 3 ft. apart, of later date. This is one of a great number of instances where we find that mediæval buildings were founded directly on Roman walls. The space Price suggested was “an open passage-way, or it may be of an alley between two buildings.” Comparison makes it certain that the walls were those of neighbouring houses in a street; similar conditions have been found at Caerwent, Silchester, etc. At the former “the shops along the main street were probably roofed with gables; this is substantiated by the finding of a finial in front of a house. The narrow space between the houses would serve to carry away the water which would drop from the eaves” (_Archæol._, 1906). The walls are shown in Fig. 28. The Bucklersbury paved passage, only just wide enough for a man to get at it, with the underlying drain, is obviously a similar space. The tradition of dividing houses in streets from one another in this way lasted into the Middle Ages (see V. le Duc’s _Dict._, “Maison”) and, of course, occasionally to modern times. By this means party walls and difficult roof gutters are avoided. From the two parallel walls we are justified in inferring a row of houses—possibly shops—and a street running to the west of them; moreover, the example suggests to some extent what continuous streets of houses must have been like. In Southwark a passage-way between houses was found 3 ft. 8 in. wide. A wall with tile paving against the outside, found under the Mansion House, suggests a similar passage. [Illustration: FIG. 28. ]
