Found this in an article on land plots in medieval Scotland
he area occupied by the residences of the
canons of Glasgow Cathedral provides a useful
example of ecclesiastical planning in an urban
setting and contrasts well with the narrow
burgage plots of a typical medieval high street.
Excavations in 1980 on the west side of Castle
Street, at the site of the Govan Manse (opposite
the site of the Bishop’s Castle), revealed an east/
west aligned ditch c 1m wide, sealed beneath a
later 17th-century building. Provand’s Lordship,
the only surviving pre-Reformation structure
in Glasgow other than the cathedral itself,
lies immediately to the south, and measures
c 16.5m wide at the street frontage. The ditch,
which lies a similar distance to the north of
Provand’s Lordship, may thus represent the
northern boundary of the property on which the
Govan Manse was built. If so, these plots of land
are approximately three times wider than the
average town plot of c 5m.
