Old Town Sanaa - Yemen 49

Sana'a (Arabic: صنعاء‎ Ṣanʿāʾ pronounced [sˤɑnʕaːʔ], Yemeni Arabic: [ˈsˤɑnʕɑ]), also spelled "Sanaa", is the capital of Yemen and the centre of San‘a’ Governorate; however the city itself is not part of the Governorate, but forms the separate administrative district of "Amanat Al-Asemah".

Sana'a is one of the oldest continuously inhabited cities in the world. At an altitude of 2,300 metres (7,500 ft), it is also one of the highest capital cities in the world. Sana'a has a population of approximately 1,748,000 (2010) making it Yemen's largest city. The old city of Sana'a, a UNESCO World Heritage Site, has a distinctive visual character due its unique architectural characteristics, most notably expressed in its multi-story buildings decorated with geometric patterns.

A UNESCO World Heritage Site is a place (such as a forest, mountain, lake, desert, monument, building, complex, or city) that is listed by the UNESCO as of special cultural or physical significance. The list is maintained by the international World Heritage Programme administered by the UNESCO World Heritage Committee, composed of 21 states parties which are elected by their General Assembly.

The program catalogues, names, and conserves sites of outstanding cultural or natural importance to the common heritage of humanity. Under certain conditions, listed sites can obtain funds from the World Heritage Fund. The programme was founded with the Convention Concerning the Protection of World Cultural and Natural Heritage, which was adopted by the General Conference of UNESCO on November 16, 1972. Since then, 186 states party have ratified the convention.

As of 2011^[update], 936 sites are listed: 725 cultural, 183 natural, and 28 mixed properties, in 153 States Parties. Italy is home to the greatest number of World Heritage Sites to date with 47 sites inscribed on the list. UNESCO references each World Heritage Site with an identification number; but new inscriptions often include previous sites now listed as part of larger descriptions. As a result, the identification numbers exceed 1200 even though there are fewer on the list.

The Arab world (Arabic: الوطن العربي‎ al-watan al-ʿarabī or Arabic: العالم العربي‎ al-ʿālam al-ʿarabī ) refers to Arabic-speaking states, territories and populations in North Africa, Western Asia and elsewhere.

The standard definition of the Arab world comprises the 22 states and territories of the Arab League stretching from the Atlantic Ocean in the west to the Arabian Sea in the east, and from the Mediterranean Sea in the north to the Horn of Africa and the Indian Ocean in the southeast, with a combined population of around 280 million people.

The sentiment of Arab nationalism arose in the second half of the 19th century along with other nationalist movements within the Ottoman Empire. The Arab League was formed in 1945 to represent the interests of the Arabs, and especially to pursue the political unification of the Arab countries, a project known as Pan-Arabism. The popular protests throughout the Arab world of late 2010 to early 2011 are directed against the governments and the associated political corruption, paired with the demand for more democratic rights.
