An observation deck is a platform situated upon a tall architectural structure or natural feature. The decks are usually fitted with railings, and to avoid accidents or suicides, the railings are often high or supplemented with a wire fence. Observation decks can be located in both indoor and outdoor settings. For photography, open observation decks are often preferred, as reflections on glass can occur with flash photography. Closed observation decks, meanwhile, have the advantage of protecting viewers from windy or stormy weather. Many observation decks are equipped with coin operated telescopes, which often offer a superior view of distant features.
