The Joseph Chamberlain Memorial Clock Tower, or colloquially Old Joe, is a clock tower and campanile located in Chancellor's court at the University of Birmingham, in the suburb of Edgbaston. It is the tallest free-standing clock tower in the world, although its actual height is the subject of some confusion. The university lists it as 110 metres (361 ft), 99 metres (325 ft), and 100 metres (328 ft) tall, the last of which is supported by other sources. In a lecture in 1945, Mr C. G. Burton, secretary of the University, stated that "the tower stands 329 ft [100 m] high, the clock dials measure 17 ft [5.2 m] in diameter, the length of the clock hands are 10 and 6 ft [3.0 and 1.8 m], and the bell weighs 5 long tons [5.1 tonnes]".
