CWM MYNACH
GRID REFERENCE: SN 753768
AREA IN HECTARES: 68.33
Historic Background
In the Medieval Period the portion of this area to the
south of the Mynach, if not all of it, formed part of Strata Florida Abbey’s
Cwmystwyth Grange. It is probable that on the Dissolution of the abbey
the Herbert family purchased this part of the grange. By the early 19th
century it had been incorporated into Thomas Johnes’s Hafod estate.
The southern portion of it is depicted on an 1834 map of the Hafod estate.
By the 16th century the abbey granges had been divided into farms, leased
out and farmed as individual units. A document of 1545-50 (Morgan 1991)
lists the farms in the Cwmystwyth grange; none of those in this area are
mentioned, though unnamed tenements are recorded. It seems likely that
along with the rest of the grange this area was divided into farms, and
possibly enclosed into the present field system by at least the end of
the Medieval Period. The tithe map provides the first good and complete
record of the area. This shows a landscape very similar to that of today.

Description and essential historic landscape
components
The upper Mynach valley, comprising the valley floor
and the lower valley sides, ranges in height from 220m to 280m. The valley
here is narrow and steep-sided. The higher valley slopes are now clothed
with forestry. Improved grazing is dominant in this area; rougher grazing
on steep slopes and rushy hollows are rare. The area is characterised
by a system of small, irregular fields that are divided by earth banks
topped with hedges. Some hedges are in good condition, but most are no
longer stock-proof and are becoming overgrown and neglected. Nevertheless
they are a very prominent component of the historic landscape. Wire fences
now provide stock-proof boundaries alongside most hedgerows. Small, scattered
stands of broadleaf woodland together with the hedgerows gives an impression
of a moderately wooded landscape. Two farms comprise the settlement pattern.
The house of one of these seems to have been recently rebuilt. The other
is a fine example of an upland farm, with a two-storey, strongly vernacular
painted stone house (but in the regional Georgian vernacular tradition),
probably dating to the early 19th century, with several stone outbuildings
set semi formally around a yard, and modern agricultural buildings.
Recorded archaeology mainly consists of the remains of
the metal mining industry. Several place-names are of interest as they
provide a certain time-depth to the landscape, and may indicate the location
of Dark Age cemeteries or monastic foundations.
This area is very well defined. To the northeast, east
and southeast, on the higher slopes of the valley side lies 20th century
forestry plantation. Unenclosed land lies to the south and an area of
large enclosures to the north.
