There are also many universities in New York, the Academy of Sciences, and many other scientific institutions. Like any other metropolis in the world, New York invites you to visit numerous museums in the city, theaters and concert halls, including the Metropolitan Opera and Carnegie Hall.

You can also appreciate the beauty of the famous Empire State Building, with a height of 102 floors, it is an example of skyscrapers, although it was built in 1829-1831. "Must see" in New York, of course, the Statue of Liberty ("Lady Liberty"), located at the mouth of the Hudson River, on the small island of Liberty. And of course, don't forget to stroll along Broadway.

It is an archipelago situated in the north Atlantic Ocean, southwest of Portugal. Its total population was estimated in 2011 at 267,785. The capital of Madeira is Funchal, which is located on the main island's south coast.

The archipelago is just under 400 kilometres (250 mi) north of Tenerife, Canary Islands. Bermuda and Madeira, a few time zones apart, are the only land in the Atlantic on the 32nd parallel north. It includes the islands of Madeira, Porto Santo, and the Desertas, administered together with the separate archipelago of the Savage Islands.

Gibraltar  is a British Overseas Territory located at the southern tip of the Iberian Peninsula. It has an area of 6.7 km2 (2.6 sq mi) and is bordered to the north by Spain. The landscape is dominated by the Rock of Gibraltar at the foot of which is a densely populated town area, home to over 30,000 people, primarily Gibraltarians. It shares a maritime border with Morocco.

In 1704, Anglo-Dutch forces captured Gibraltar from Spain during the War of the Spanish Succession on behalf of the Habsburg claim to the Spanish throne. The territory was ceded to Great Britain in perpetuity under the Treaty of Utrechtin 1713. During World War II it was an important base for the Royal Navy as it controlled the entrance and exit to the Mediterranean Sea, which is only 8 miles (13 km) wide at this naval choke point. It remains strategically important, with half the world's seaborne trade passing through the strait. Today Gibraltar's economy is based largely on tourism, online gambling, financial services and cargo ship refuelling.

The sovereignty of Gibraltar is a point of contention in Anglo-Spanish relations because Spain asserts a claim to the territory. Gibraltarians rejected proposals for Spanish sovereignty in a 1967 referendum and, in a 2002 referendum, the idea of shared sovereignty was also rejected.
