Lighthouses are constructed of wood, granite, brick, sandstone, steel, cast iron, reinforced concrete, marble, and aluminum.  They represent many shapes:  cylindrical, conical, square, octagonal, square pyramidal, and triangular.  Additionally, some light towers are separate structures, some are attached by walkways, and some are integral or built right-into the keeper's quarters.  Politics, cost, location, special needs, geography at the site, and available technology at the time of construction influenced lighthouse construction and design throughout history.

The USCG photos below show examples of various shapes and attachments found on the Great Lakes and two (caisson & screwpile) that are found in coastal ocean waters.
