Belém Tower (in Portuguese Torre de Belém, [ˈtoʁ(ɨ) dɨ bɨˈlɐ̃ĩ]) or the Tower of St Vincent is a fortified tower located in the Belém district of Lisbon, Portugal, and is an UNESCO World Heritage Site (along with the nearby Jerónimos Monastery) due to the significant role it played in the Portuguese maritime discoveries of the era of the Age of Discoveries. The tower was commissioned by King John II to be both part of a defense system at the mouth of the Tagus River and a ceremonial gateway to Lisbon.

The tower was built in the early sixteenth century and is a prominent example of the Portuguese Manueline style, but it also incorporates hints of other architectural styles. The structure was built from lioz limestone and is composed of a bastion and the 30 meter (100 foot), four story tower. It has incorrectly been stated that the tower was built in the middle of the Tagus and now sits near the shore because the river was redirected after the 1755 Lisbon earthquake. In fact, the tower was built on a small island in the Tagus River near the Lisbon shore.

Portugal /ˈpɔrtjəɡəl/ , officially the Portuguese Republic (Portuguese: República Portuguesa), is a country located in southwestern Europe on the Iberian Peninsula. Portugal is the westernmost country of mainland Europe and is bordered by the Atlantic Ocean to the west and south and by Spain to the north and east. The Atlantic archipelagos of the Azores and Madeira are also part of Portugal.

The land within the borders of today's Portuguese Republic has been continuously settled since prehistoric times. Gallaeci, Lusitanians, Celtici, Cynetes, Phoenicians, Carthaginians Romans and many Germanic tribes such as the Suevi, the Buri and the Visigoths, all left their influence on what is today Portuguese territory. The territory was integrated in the Roman Empire as the province of Lusitania and Roman settlers strongly influenced Portuguese culture, particularly the Portuguese language, mostly derived from Latin. In the 5th century, after the fall of the Roman empire, it was occupied by different Germanic tribes. In the early 8th century the Muslim Moors conquered the Christian Germanic kingdoms, occupying most of the Iberian Peninsula. Later, during the Christian Reconquista (Reconquering), the County of Portugal was settled, as part of the Kingdom of Galicia. Portugal emerged during the 12th century from this brief earldom and would establish almost its entire modern-day borders in 1249.

This is a specific list of the UNESCO World Heritage Sites in Europe. Cyprus, Israel, Turkey, Georgia, Azerbaijan, Armenia and the Caucasian and Siberian parts of Russia are included both in this list and in the list of sites in Asia. Overseas sites of France, the Netherlands, UK and Denmark are included here, but are also repeated in the geographically relevant lists. Kazakhstan, despite having a small portion lying in Europe is to be found under Asia, where both its world heritage sites are listed. Israeli sites are listed here, since the alternative "Arab States" grouping is politically unacceptable.

Sites marked with an asterisk (*) are also included on the List of World Heritage Sites in danger.

Europe (/ˈjʊɹəp/, -əp) is, by convention, one of the world's seven continents. Comprising the westernmost peninsula of Eurasia, Europe is generally divided from Asia to its east by the water divide of the Ural Mountains, the Ural River, the Caspian Sea, the Caucasus Mountains (or the Kuma-Manych Depression), and the Black Sea to the southeast. Europe is bordered by the Arctic Ocean and other bodies of water to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south, and the Black Sea and connected waterways to the southeast. Yet the borders for Europe—a concept dating back to classical antiquity—are somewhat arbitrary, as the term continent can refer to a cultural and political distinction or a physiographic one.

Europe is the world's second-smallest continent by surface area, covering about 10,180,000 square kilometres (3,930,000 sq mi) or 2% of the Earth's surface and about 6.8% of its land area. Of Europe's approximately 50 states, Russia is the largest by both area and population, while Vatican City is the smallest. Europe is the third-most populous continent after Asia and Africa, with a population of 731 million or about 11% of the world's population. However, according to the United Nations (medium estimate), Europe's share may fall to about 7% by 2050. In 1900, Europe's share of the world's population was 25%.
