Ancient lighthouses

 

Before the development of clearly defined ports, mariners were guided by fires built on hilltops. Since raising the fire would improve the visibility, placing the fire on a platform became a practice that led to the development of the lighthouse. In antiquity, the lighthouse functioned more as an entrance marker to ports than as a warning signal for reefs and promontories. The most famous lighthouse structure from antiquity was the Pharos of Alexandria, although it collapsed during an earthquake centuries later.

The intact Tower of Hercules give insight into ancient lighthouse construction.

The modern era of lighthouses began at the turn of the 18th century, as lighthouse construction boomed in lockstep with burgeoning levels of transatlantic commerce. Advances in structural engineering and new and efficient lighting equipment allowed for the creation of larger and more powerful lighthouses, including ones exposed to the sea. The function of lighthouses shifted toward the provision of a visible warning against shipping hazards, such as rocks or reefs.

Over the centuries, the improvements made by the Man have created lighthouses powerful enough to transmit their light over many miles. Lighthouses are essentially used to guide ships during storms or fog.

Nowadays, the modern lighthouses use electric devices and are not usually tended by a keeper.
