Sambro Island Lighthouse , sometimes also Sambro Lighthouse , is a lighthouse ( English Lighthouse ) in the Canadian province of Nova Scotia . It stands on the archipelago of the same name , about 12 nautical miles (22 kilometers) south of the port of Halifax . The lighthouse has been in operation since 1759 and is the oldest surviving lighthouse in America .
history
The lack of a lighthouse for the safe access to the port of Halifax was discovered shortly after the establishment of the first settlement . Construction was approved in 1758 and the first beacon went into operation on Sambro Outer Island in 1759. The stone tower was 60 ft (18.3 m ) high and had a fire height of 115 ft (35.1 m ). The beacon was initially operated with oil and accordingly quickly the range was reduced by sooty windows. In addition, the lamp was not ignited again and again when it went out. These restrictions led to the loss of the sloop Granby in 1771 . After the investigation into the ship accident , responsibility for the lighthouse was transferred to the Navy in 1772.
In 1864 the beacon was given an iron lantern and in 1906 the tower was lengthened by 22 ft (6.7 m ). A first-order Fresnel lens was then installed on the higher tower .
In January 1950, the observed beacon guards that the lighthouse fluctuated. Some stones had loosened in the foundation from broken mortar . The tower base was then reinforced with a two meter high concrete collar.
In 1966 the Fresnel lens was replaced by a rotating airfield light ( English Aerobeacon ) of the type DCB-36. The lantern was then removed and the tower was given its current height of 82 ft (25 m ).
After the submarine cable broke several times , the beacon and foghorn were switched to solar energy on March 28, 2008 and the airfield light was replaced by the TRB-400 system (similar to the VRB-25 ).
The lighthouse has been recognized as a National Historic Site of Canada since 1996 .
