hello there,welcome to solsarin , on this post we’ll find”which state has the most lighthouses?” and leard more about light houses.
What is a lighthouse?
A lighthouse is a high tower equipped with a bright light and lenses that help guide ships to port at night and alert sailors about sandbars, reefs, and rocky coastlines.
What are lighthouses for ?
Each lighthouse features a large lamp on top of the building. At night, it lights up when everything around is dark.
The lamp, installed in the lantern room with glass windows, works as a flashlight and allows boats and ships to sight land from far away at sea.
The light beam system is so powerful and effective that it helps sailors lost at sea find their way back to shore, even during storms and foggy nights.
Modern lighthouses use automated, high-intensity lights that emit brief and omnidirectional flashes and coded aids to navigation (color, period, and phase).

Lighthouses are somewhat nostalgic today.
With electricity and modern navigational systems on boats, they have become outdated.
They help the odd boater out of a storm now and then, but we don’t rely on them like we used to.
Back at the turn of the century, lighthouses were lifesavers.
They were usually built on capes or coastlines that were particularly difficult to navigate.
They have been around since before the U.S. was a country. Americans erected more in 1910 than any other year. Of the 267 made that year, 140 of them were in Michigan!
Maine may be known as The Lighthouse State, but Michigan has more of them.
The Great Lakes surround the state on three sides.
Lake Michigan curves around it in a U-shape creating the left, top, and right borders. Lake Erie finishes the right perimeter off at the bottom. Lake Michigan is known as the deadliest Great Lake.
It has rip currents that terrify beach-goers every summer.
Back in the time before electric lights, those strong currents caused even deadlier problems for ships traveling Lake Michigan. Without lighthouses, those ships would never have made it to port safely. Naturally, they had plenty of them to go around.
The Oldest Lighthouses In The U.S.
Wood-burning fires powered the first lighthouses in America. Lightkeepers kept the braziers going to help ships find their way. The first such lighthouse stood on Little Brewster Island in Boston, in colonial New England. Its keepers helped ships sail murky waters before the birth of the USA! In fact, the original tower was destroyed by the British in the American Revolution.
The oldest continuously used lighthouse in the states is in Sandy Hook, New Jersey. The people in the area had talked about erecting a tower there since 1679. The large, jutting sandbar Sandy Hook was named for was a navigational hazard for sailors. It took many ships down before the community installed the lighthouse in 1764.
The Tallest Lighthouse In The U.S.
Off the coast of Cape Hatteras, NC lies the infamously dangerous Diamond Shoals. The shoals are shifting, underwater sandbars. In the days before electricity, they took down countless ships. The government finished the first lighthouse at Cape Hatteras in 1803. Unfortunately, it wasn’t tall enough to guide the ships around the shoals. They kept sinking along that unpredictable shore. Over the next 70 years, the government added 110 feet to the lighthouse making it 200 feet and the tallest lighthouse in the U.S.
In 1999, the effects of erosion threatened to level the U.S.’s tallest lighthouse. Rather than let that happen, the community came together and moved it to safer ground 3000 feet inshore. You can visit it today. It offers a spectacular view of the stars in the summertime.
Statue Of Liberty
Did you know that the most iconic symbol of America is also a lighthouse? The beacon in the torch doesn’t just give newcomers hope. It also protected ships coming into the harbor in New York City, which is in the state of New York. When the statue was assembled in 1886, electric lights were brand new.
lighthouse, structure, usually with a tower, built onshore or on the seabed to serve as an aid to maritime coastal navigation, warning mariners of hazards, establishing their position, and guiding them to their destinations. From the sea a lighthouse may be identified by the distinctive shape or colour of its structure, by the colour or flash pattern of its light, or by the coded pattern of its radio signal. The development of electronic navigation systems has had a great effect on the role of lighthouses. Powerful lights are becoming superfluous, especially for landfall, but there has been a significant increase in minor lights and lighted buoys, which are still necessary to guide the navigator through busy and often tortuous coastal waters and harbour approaches. Among mariners there is still a natural preference for the reassurance of visual navigation, and lighted marks also have the advantages of simplicity, reliability, and low cost. In addition, they can be used by vessels with no special equipment on board, providing the ultimate backup against the failure of more sophisticated systems.
History of lighthouses
Lighthouses of antiquity
The forerunners of lighthouses proper were beacon fires kindled on hilltops, the earliest references to which are contained in the Iliad and the Odyssey (c. 8th century BCE).
The first authenticated lighthouse was the renowned Pharos of Alexandria, which stood some 350 feet (about 110 metres) high. The Romans erected many lighthouse towers in the course of expanding their empire, and by 400 CE there were some 30 in service from the Black Sea to the Atlantic.
These included a famous lighthouse at Ostia, the port of Rome, completed in 50 CE, and lighthouses at Boulogne, France, and Dover, England. A fragment of the original Roman lighthouse at Dover still survives.
The Phoenicians, trading from the Mediterranean to Great Britain, marked their route with lighthouses.
These early lighthouses had wood fires or torches burning in the open, sometimes protected by a roof. After the 1st century CE, candles or oil lamps were used in lanterns with panes of glass or horn.
The beginning of the modern era
The development of modern lighthouses can be said to have started about 1700, when improvements in structures and lighting equipment began to appear more rapidly.
In particular, that century saw the first construction of towers fully exposed to the open sea. The first of these was Henry Winstanley’s 120-foot-high wooden tower on the notorious Eddystone Rocks off Plymouth, England.
Although anchored by 12 iron stanchions laboriously grouted into exceptionally hard red rock, it lasted only from 1699 to 1703, when it was swept away without a trace in a storm of exceptional severity; its designer and builder, in the lighthouse at the time, perished with it.
It was followed in 1708 by a second wooden tower, constructed by John Rudyerd, which was destroyed by fire in 1755. Rudyerd’s lighthouse was followed by John Smeaton’s famous masonry tower in 1759. Smeaton, a professional engineer, embodied an important new principle in its construction whereby masonry blocks were dovetailed together in an interlocking pattern.
Despite the dovetailing feature, the tower largely relied on its own weight for stability—a principle that required it to be larger at the base and tapered toward the top. Instead of a straight conical taper, though, Smeaton gave the structure a curved profile.
Not only was the curve visually attractive, but it also served to dissipate some of the energy of wave impact by directing the waves to sweep up the walls.
Owing to the undermining of the foundation rock, Smeaton’s tower had to be replaced in 1882 by the present lighthouse, constructed on an adjacent part of the rocks by Sir James N. Douglass, engineer-in-chief of Trinity House.
In order to reduce the tendency of waves to break over the lantern during severe storms (a problem often encountered with Smeaton’s tower), Douglass had the new tower built on a massive cylindrical base that absorbed some of the energy of incoming seas. The upper portion of Smeaton’s lighthouse was dismantled and rebuilt on Plymouth Hoe, where it still stands as a monument; the lower portion or “stump” can still be seen on the Eddystone Rocks.
Following the Eddystone, masonry towers were erected in similar open-sea sites, which include the Smalls, off the Welsh coast; Bell Rock in Scotland; South Rock in Ireland; and Minots Ledge off Boston, Massachusetts, U.S. The first lighthouse of the North American continent, built in 1716, was on the island of Little Brewster, also off Boston. By 1820 there were an estimated 250 major lighthouses in the world.
How do lighthouses survive storms?
From base up, they were built by precisely chiseled, interlocking granite blocks that could withstand the pounding of the sea waves. These men, in the most treacherous conditions, built the tall lighthouses that warned the sailor of treacherous rocks and reefs that could rip ships apart. They also invented the lamps and lenses installed in these skyscrapers of the seas.
