The Atlantic Entrance Range Middle Lighthouse is an active light located about 100 metres to the north east of the Gatun Locks, the first set of locks encountered when entering the Panama Canal from the Caribbean/Atlantic side. It is south of Limon Bay and the city of Colon, Panama. This light was constructed during the original construction of the Panama Canal (between 1904 and 1914) and activated in 1914. It is a 23 metre (75 foot) tall white concrete tower. Photos taken in March 2016.
