The Emley Moor television mast in Huddersfield, West Yorkshire. The structure is a tapered, reinforced concrete tower. It is the tallest freestanding structure in the United Kingdom at a height of 330.4 metres (1,084 ft). Reaching the Tower Room at the top of the concrete part of the tower at 275 m (900 ft) involves a seven-minute journey by lift. The antenna structure above this is a further 56 m (184 ft). Its foundations penetrate 6.1 m (20 ft) into the ground and the whole structure, including foundations, weighs 11,200 tonnes. It was designed by Ove Arup and Partners. When it was built, it was the third-tallest freestanding structure in Europe, after the Ostankino Tower at 540 metres (1,772 ft) and the Fernsehturm Berlin (current height 368 metres (1,207 ft)). The top of the tower is 594 m (1949 ft) above sea level due to the site's elevated position on the Eastern edge of the Pennines. In 2002, the UK Government declared Emley Tower a Grade II Listed Building of 'significant architectural or historic interest'.
