Turret, tower and public clocks

The first mechanical clocks of the late thirteenth and fourteenth centuries were large iron striking clocks in towers, monasteries and cathedrals, driven by falling weights and controlled by a verge escapement with a foliot or wheel balance. They struck a bell rather than displaying the time, and only gradually acquired dials. Public clocks ordered civic life, regulating markets, work and worship.

From the seventeenth century the pendulum and then the anchor and pinwheel escapements made turret clocks far more accurate. In the nineteenth century firms such as Dent, Smith of Derby, Gillett & Johnston, J. F. Weule and Collin made cast-iron flatbed movements, and Edmund Beckett Denison's gravity escapement for the Great Clock of Westminster (1859) became the standard for accurate tower clocks.
