The Brooklyn Bridge, built between 1869 and 1883, connects Manhattan with New York's most populous borough, Brooklyn. The bridge is one of the most famous and magnificent landmarks in New York City.
At the time of construction, Brooklyn - founded by Dutch settlers in the 17th century - was still an independent city. In fact it was even one of the country's largest cities. In 1898, fifteen years after the opening of the Brooklyn Bridge, Brooklyn citizens decided in a close vote to become a borough of New York.
The construction of the Brooklyn Bridge started in 1869 and took fourteen years to complete. At the time many saw the construction of such a large bridge as a folly.
The driving force behind the whole project, John Roebling, was a German immigrant who had worked for the Prussian government as a bridge and road builder. He launched the idea of building a bridge across the East River after he had taken a ferry across the river that ended up stuck in the ice.
John Roebling would never get to see the bridge he had designed: he died after crushing his foot in an accident. He wasn't the only one to lose his life during the construction: 20 of the in total 600 workers died while working on the bridge. The son of John Roebling, Washington Roebling, took over the leadership of the project but he suffered from the caisson-disease as a result of the works on the pillars of the bridge and was on his deathbed during the inauguration. That day, May 24, 1883, about 150,000 people crossed the bridge
Roebling had not just made a bridge that looked incredibly strong, it also turned out to be just as strong in reality. A mesh of cables of which the four strongest have a diameter of 11 inches (28 cm) are anchored in the ground and keep the bridge from collapsing
But even if the four strongest cables would snap, the other cables would still be sufficient to support the bridge. Roebling even claimed that the bridge wouldn't collapse without any cables, it would merely sag.
But even after the inauguration, many New Yorkers were not convinced the bridge was safe. So as to prove the doubters wrong, P.T. Barnum led a caravan of circus animals - including a herd of 21 elephants - across the bridge in 1884.
The Brooklyn Bridge ranks as one of the greatest engineering feats of the 19th century and remains one of New York's most popular and well known landmarks.
The impressive bridge spans the East river between Brooklyn and Manhattan and stretches for a length of 5989 ft, about 1.8 km. The span between the large towers measures 1595.5 ft (486 meters). This made the Brooklyn Bridge the world's largest suspension bridge
The most noticeable feature of the Brooklyn Bridge are the two masonry towers to which the many cables are attached. The towers with large Gothic arches reach a height of 276 ft (84 meters), at the time making them some of the tallest landmarks in New York. Roebling claimed that the monumental towers would make
Brooklyn Bridge, New York
the bridge a historic monument. He was proven right when the bridge officially became a national monument in 1964
An elevated pedestrian path not only gives you the opportunity to cross the river without being bothered by the traffic that rushes past a level below, but it also offers a great view of the bridge's towers as well as downtown Manhattan's skyline. The views alone attract millions of visitors to this bridge each year

Heaven Insects - butterflies and moths (butterflies) is an insect belonging to the order Lepidoptera, or 'winged insect scales' (lepis, scales and pteron, wings).
Simply put, butterflies are distinguished from moths aka butterfly night based on the time of active and physical attributes. Butterflies are generally active during the day (diurnal), while the moths are mostly active at night (nocturnal),
r sure. (van Mastrigt and Rosariyanto, 2005).
Butterflies and moths so many kinds, in Java and Bali alone recorded more than 600 species of butterflies. Moth kind so far have not made a full list, but suspected there were hundreds of different types (Whitten et al., 1999). Butterfly became one of the few types of insects are harmless to humans.
Cethosia Myrina which is also known by the name of butterfly angel or butterfly wings Sulawesi or brown lace accented This butterfly has a wide wing span of up to 75 mm. Located on the island of Sulawesi South Baian and north, up to a butterfly endemic to Sulawesi.
Subspecies: Cethosia Myrina Myrina
