Tŷ Canol National Nature Reserve

Tŷ Canol Woods are an ancient woodland in the Tŷ Canol National Nature Reserve which lies south of the village of Felindre Farchog, Pembrokeshire, Wales, between the Preseli Mountains and the north Pembrokeshire coast. The site is designated as an SSSI (Site of Special Scientific Interest), NNR (National Nature Reserve) and SAC (Special Area of Conservation). After the glaciers made their final retreat from Wales around 11,500 years ago, it took time to transform the barren landscape into a lush woodland. But gradually Arctic plants were joined by shrubs, then progressively birch, Scots pine, oak, alder and hazel trees colonised. By around 6,000 years ago, an extensive deciduous woodland may have covered even the uplands of Wales. 1,000 years later the woodlands started to diminish in size and number thanks to natural and human influences. With trees over 800 years old, Tycanol is one of the few remaining ancient woodlands in Wales. The site is important not only for its ancient oaks, but also for the many rocky outcrops. Both trees and rocks are covered with mosses and nearly 400 species of lichen, many of which are rare.

Cemais (sometimes spelled Kemes after one of the several variations found in Medieval orthography) was an ancient cantref of the Kingdom of Dyfed, from the 11th century a Norman Marcher Lordship, from the 16th century a Hundred, and is now part of Pembrokeshire, Wales. It occupied the coastal area between the Teifi estuary and Fishguard, and the northern and southern slopes of the Preseli Hills, covering an area of approximately 140 square miles (360 km2). The Afon Nyfer divided it into two commotes: Cemais Is Nyfer to the north and Cemais Uwch Nyfer to the south.: 25 

That Roundhouse is a roundhouse sited in woods within the Pembrokeshire Coast National Park near the town of Newport in Wales. It was constructed without planning permission during the winter of 1997/1998 by Tony Wrench and Jane Faith and helpers as part of the then secret Brithdir Mawr intentional community. The structure was discovered in 1998, challenged by the authorities, and threatened with demolition; it was granted retrospective planning permission in September 2008, with a review in three years. The “radical experiment” has attracted considerable media attention in relation to issues surrounding green building, affordable housing, low-carbon building, low-impact development and sustainable living.

Waun Mawn (Welsh for "peat moor") is a megalithic site in the Preseli Mountains of Pembrokeshire, Wales. Following excavations in 2018, it became the site of a supposed dismantled Neolithic stone circle. The diameter of the postulated circle was estimated to be 110 m (360 ft), making it the fifth largest diameter for a British stone circle, after Avebury, Stanton Drew, Karl Lofts, Long Meg, and The Ring of Brodgar. The site is located around 1 mile (1.6 km) to the south west of Brynberian. This tract of moorland sits on the southern slopes of the 339 m (1,112 ft) hill top of Cnwc yr Hŷdd ("cock of the corn"), just to the north of the broad east-west ridge of the Preseli range. There are four stones at the site today, one standing and three prostrate. Nearby are the Troed y Rhiw ("foot of the hillside") standing stones and to the west of the main group is another solitary standing stone, the 'Waun Mawn Stone', measuring some 2.3 m (7 ft 7 in) high.
