AMOCO OIL REFINERY
GRID REFERENCE: SM 883084
AREA IN HECTARES: 163
Apart from a number of fields that lie within the perimeter fence, this
historic landscape character area comprises an oil refinery. It lies within
the parishes of Herbrandston and Robeston West. Most of the present farms
and landholdings can be identified with medieval manors. These manors
were subject to a complex process of division and sub-infeudation following
the break-up of the Earldom of Pembroke in 1247. The north half of the
area lay within the medieval Manor of Robeston, a member of the Lordship
of Haverford which was probably not established until the 14th century.
Extending into the west of the area, Rickeston comprised ¼ of a
knight’s fee, held directly of the Earls of Pembroke as their share
of the lordship. The southern part of the area represented the Barony
of Walwyn’s Castle’s share of Herbrandston, which comprised
2 ¾ carucates held of the barony ‘by homage’. However,
the various ownerships did not appear to be reflected in any different
tenurial arrangements, as a homogenous pattern of enclosure resulted.
Prior to the construction of the refinery the area consisted of an agricultural
landscape of regularly shaped fields. According to late estate maps these
fields changed little between the late 18th century and the construction
of the refinery. Refinery construction began in 1971 and it was opened
