About
Twmbarlwm, also known as Twm Barlwm, Twyn Barlwm or locally known as "the Twmp" (translation: hump), the Nipple or the Pimple because of the mound that lies at its summit, is a hill situated 2 km (1.2 mi) to the northeast of Risca in South Wales. It is often mistakenly referred to as a mountain but is actually a hill due to being under 600 m (2,000 ft). It is 419 m (1,375 ft) high and is a well-known landmark throughout the region. It commands extensive views across what is now the M4 corridor, over Newport and Cwmbran - with part of it coming into Cwmbran - and out over the Bristol Channel.
