Historical Information:

  • In 1857 a lantern was hoisted on top of an 18 ½ ‘cast-iron pole. * In 1870 the first “true” lighthouse was built. The light was fitted with a sixth order Fresnel lens. The current fog bell tower was built in 1882 to house the 1400 fog bell. 
  • In 1885 the keeper’s house was built near the bell tower. 
  • As the fort grew the gun batteries and pier blocked the light from the second tower. There were several complaints about the quality of the light. 
  • Funds were requested to heighten the light tower, but the request was denied. In an effort to address concerns about the obscured light the 1901 the bell tower was modified to raise the height of the bell tower and a small automated fixed white light was installed. This was supposed to be a temporary fix, but a replacement tower was never built. In 1901 the tower built in 1870 was also torn down. 
  • In 1920 the fixed white light was changed to a fixed red light.
  • In 1954 the station became unmanned.
  • In 1970 the bell mechanism broke and was not repaired. 
  • In 2005 the tower was turned over to the National Park Service.
