Zimapan is a nineteenth
century, T-shaped house situated in Tregullow, Scorrier, near Redruth, Cornwall. It was built
end-on to the road (B3298) and faces south. A number of extensions have been added on to the
original bungalow since it was first built.

from west to east. Zimapan is less than a mile from Scorrier House, a grand mansion
owned for generations by the Williams family who made their fortune in the Cornish mining

Scorrier and Tregullow are small,
separate Cornish hamlets. Zimapan, whose postal address is
(confusingly) 'Tregullow, Scorrier', is situated in the Parish of Gwennap, near Redruth, Cornwall, just
outside the Parish of St Day. The area used to be a bustling Cornish mining community, where
tin, copper and silver were intensively mined until around 1880.
Spoil heaps rich in
arsenic and wolfram
The mining of copper at
the Great Wheal Busy (Chasewater Mine) near Scorrier, produced arsenic as a by-product of the
copper-refining process2. In the early 20th century, the resulting spoil heaps left behind on the
surface were worked over for their rich arsenic and wolfram content3.
According to Cornwall County
service, Zimapan currently lies at the intersection between the two parish boundaries
of St Day and Gwennap. The area to the left of the wishbone-like intersection is the Parish
of St Day, while Gwennap Parish lies to the right, and includes Zimapan House as it is now
Scorrier's now disused Great
Western Railway (mainline) station was closed in the 1960s as part of the highly unpopular
nationwide reorganisation of British railways by the then Minister of Transport, Beeching.
Today, Scorrier comprises about 50 houses and Tregullow only four4.
Parts of Cornwall and Devon, which
include the area in which Zimapan is situated, were
designated a World Heritage Site by UNESCO in 2006.
