817-1/20/312 Icehouse approx 35m S of Postern,
Hertford Castle (Hertford Castle
demolished)
GV II
Icehouse. c1795-1800. Red brick, header bond. Subterranean
chamber with earth mound above, approached through reset-iron
gate below modern concrete slab, into arched entrance. Dogleg
plan, 4.7m long with red brick floor and segmental arched
roof, and 4 frame rebates leading to circular well approx 3.5m
diameter and 3.2m depth, with header bonded brick
hemispherical domed roof and English bond conical lower
section; brickwork discoloured and calcified but appears
originally to have been red.
The well forms a lip at the end making the access hole small;
the well door was positioned sloping over the well. A small
window appears to have been cut out of the left wall of the
entrance tunnel between the second and third door; its purpose
is unclear as it now reveals only the surrounding earth mound.
Construction of the icehouse, on the thin islet between the 2
historic castle moats, dates from the late C18 major
alterations undertaken by the Marquis of Downshire.
