here is the story: Some of the earliest lighthouses were simply hillside bonfires. Today, a lighthouse is commonly known as a type of tower that shines a large lamp out to the sea. The light helps to mark dangerous areas along a coast. A lighthouse also gives notice to a ship that land is near.
Many lighthouses were constructed in the 17th century. The first lighthouse in the U.S. was built in 1716 in Boston Harbor. Nearly 1,000 lighthouses were built by 1900 in the U.S. After this point, many lighthouses were abandoned and became rundown as a result.
In the U.S., the coast guard oversees the lenses and lamps of the country’s lighthouses. In more recent years, the destruction of lighthouses has been rising. Groups have formed in order to restore lighthouses. Often, these lighthouses are made into parks, museums, research centers, and even inns or hotels to stay at overnight.
