NHER 1172 (Monument record) - Medieval causeway, 13 Norfolk Street

Systematic observation and casual discoveries.
Two deep trenches around the north and east perimeters of the site, with several deep stanchion holes, showed that the surface of natural clay, at about 2.5m to 2.75m (8 to 9 feet) O.D. over most of the site, rose sharply to about 3.6m to 3.95m (12 to 13 feet) O.D. against Norfolk Street. Between 4.3m and 5.5m (14 and 18 feet) O.D. above a massive silt layer, the remains of a timber and brushwood corduroy were exposed in the face of the machine-cut trench along Norfolk Street.
The trench was shored before the feature could be investigated, but it apparently bore no relationship to the medieval street frontage wall. It probably represents the artificial heightening of a natural bank along Damgate to form a causeway (S1). The causeway is reflected in the street name and referred to in 13th and 14th century documents.
No pottery was associated with the feature and the only finds from the site were a few sherds of Grimston cooking pot and jug, and a 15cm (6 inch) high Raeren jug (retained by the finder).
