Onshore Lighthouse Construction Types--Reinforced Concrete

Concrete towers reinforced with steel began to replace brick masonry towers at the beginning of the 20th century; the first was constructed in 1908 at Point Arena, California. Steel in concrete structures provided the tensile properties that concrete alone lacks. Most major reinforced concrete towers are found on the West Coast where they are best adapted to the dangers of earthquake damage. A series of art-moderne reinforced concrete lighthouses were built along the Alaska coast in the 1920s and 1930s, replacing earlier deteriorated wooden structures.

Surviving examples of reinforced concrete lighthouse towers include:
