There are many [[structures]] that may have clocks or clock faces attached to them and some structures have had clocks added to an existing structure. According to the [[Council on Tall Buildings and Urban Habitat]] a structure is defined as a building if at least fifty percent of its height is made up of floor plates containing habitable floor area. Structures that do not meet this criterion, are defined as [[towers]]. A clock tower historically fits this definition of a tower and therefore can be defined as any tower specifically built with one or more (often four) [[clock]] [[Clock face|faces]] and that can be either freestanding or part of a [[church (building)|church]] or municipal building such as a [[town hall]]. Not all clocks on buildings therefore make the building into a clock tower.

The mechanism inside the tower is known as a [[turret clock]]. It often marks the hour (and sometimes segments of an hour) by sounding large [[bell (instrument)|bells]] or [[chime (bell instrument)|chime]]s, sometimes playing simple musical phrases or tunes. Some clock towers were previously built as [[Bell towers]] and then had clocks added to them. As these structures fulfil the definition of a tower they can be considered to be clock towers.
