Lighthouses demonstrate the creativity and ingenuity of the
people who built them. The architects and builders of lighthouses
used proven techniques as well as developed new ones in an
effort to provide better navigational aids. The ability to
place lighthouses on small islands of rock amid the crashing
waves of the open sea or reaching hundreds of feet toward
the sky from a sandy shore is the result the cumulative and
ever-advancing field of architecture.
Although Lighthouses have been built with a variety of materials,
such as wood, stone, concrete and iron in a variety of different
styles, such as piles, caisson, and various tower types, they
all have had a basic structural purposes in common: to place
powerful lights atop uniquely marked structures in a favorable
position for alerting ships of nearby hazards and guiding
them along our coasts and harbors.
