"Twmbarlwm also known as Twm Barlwm, Twyn Barlwm, or locally known as \"The twmp\" (translation: hump) 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 600m. It is 419 m (1,375 ft) high and is a well known landmark throughout the region."@en . "48.0"^^ . .
