Historic Landscape Characterisation

Caernarfon/ Nantlle – Area 40 Treflan PRN 15739


This view, which looks north east, is centred on the remains of the disused slate quarry, while one of the farms and some of the irregular enclosures are visible on the mountain side above the valley bottom (area 35).



Historical background

This area includes the site of a medieval township, and was latterly part of the Wynnstay estate. The smallholdings of Ty Ucha'r Ffordd, Pentre Uchaf, Pentre Isaf, Bryn y Pistyll, Ty'n y Gerddi, Bryneithin and Hafod Oleu were all in existence by the 1740s. A woollen mill was active by 1730, providing clothes for the Drws y Coed miners. In 1803 the estate was sold to the partnership working the Cilgwyn and Cefn Du Slate Quarries. In 1819 the Company sold a quarter of the estate to John Evans, and the remainder in 1825. It was again disposed of (by auction) in 1845, and was sold to the occupier.

Key historic landscape characteristics

Relict and industrial archaeology, field pattern

The area is quite distinctive, lying below open mountainside and above the river floodplain. It contains a number of disparate elements, which together make for an interesting (and potentially informative) historic area. These elements include the place-name element of a medieval township (one of the most inland of such in this area), several deserted rural settlements, several farmhouses, a small chapel, the remains of a slate quarry (which includes an incline) and more recent settlement. It is apparent that many of the farmhouses, although substantially built, have field names rather than names which indicate a complete holding, for instance, Gwastadfaes and Ty'n y Wern. There is also a large caravan park here.
