The third and top floor of the Eiffel Tower is 276.13 metres above ground level. Only accessible by lift, it consists of an enclosed space of 1,148 sq. ft. (350 m²) featuring orientation panels. A few steps higher, the outdoor platform that tops it reaches almost 279 metres. Sometimes called the “fourth floor”, it is the highest point open to the public, just below the television and radio masts that crown the monument. From the perspective of the top of the tower, you can see the Grand Palais Ephémère – designed by Jean-Michel Wilmotte – and the facade of the Ecole Militaire.
