Pemaquid Point Lighthouse Maine
Built in 1827 but due to the fact salt water was used in the mortar mix the lighthouse began to crumble and was rebuilt in 1835.
The original light was an Argand-Lewis parabolic reflector, lit with candles and with a visibility of 2 miles. Augustin Fresnel invented a superior way of focusing light in the early 1850s and most lighthouses in the US were converted to the Fresnel Lens. Pemaquid Point received a fourth order Fresnel in 1856. The Lightkeeper's house was built in 1857.
The station was automated in 1934. The fog bell is in place on an outbuilding close to the escarpment.
