An observation tower is a structure used to view events from a long distance and to create a full 360 degree range of vision. They are usually at least 20 metres (65.6 ft) tall and made from stone, iron, and wood. Many modern towers are also used as TV towers, restaurants, or churches. The towers first appeared in Germany at the end of the 18th century, and their numbers steadily increased, especially after the invention of the elevator.
Observation towers that are used as guard posts or observation posts over an extended period to overlook an area are commonly called watchtowers instead.

Famous quotes containing the words observation and/or tower:
“It is, in both cases, that a spiritual life has been imparted to nature; that the solid seeming block of matter has been pervaded and dissolved by a thought; that this feeble human being has penetrated the vast masses of nature with an informing soul, and recognised itself in their harmony, that is, seized their law. In physics, when this is attained, the memory disburthens itself of its cumbrous catalogues of particulars, and carries centuries of observation in a single formula.”
—Ralph Waldo Emerson (18031882)
“If God made me a princess, why didnt he take a little more time and make my hair so it wouldnt snarl?”
—Robert N. Lee. Rowland V. Lee. Princess, Tower of London, while the Princess mother is combing her hair (1939)
