Mention the term “observation tower” and many will think of the Eiffel Tower in Paris, France or the Space Needle in Seattle, the United States. They are among the most recognisable landmarks in the world that were designed specifically as observation towers.

Historically, observation towers were built as guard posts or watch towers to oversee a large extent of an area. Modern towers are designed with viewing decks, restaurants, galleries and souvenir shops to draw in visitors.
