Observation, Communication and Landmark Towers

Towers this atlas records under Monuments, Towers and Commemorative Structures that are built chiefly to be seen from or looked out from rather than to house a clock or bells: observation and communication towers, the Eiffel Tower and its observation decks, the Lighthouse of Genoa's functioning navigational tower, medieval Italian landmark towers such as the Guinigi Tower, Torre dei Lamberti and Torre del Mangia, and Durlston Castle, a Victorian folly built as a scenic coastal viewpoint. Belongs here: any tower this subcategory records that is not specifically a clock or bell tower. Does not belong here: a clock or bell tower, gathered under this subcategory's own Historic Clock and Bell Towers group instead.
