A cover from France with 2 UNESCO stamps.
The United Nations Educational, Scientific and Cultural Organization (UNESCO) is a specialized agency of the UN based in Paris. UNESCO provides a few stamps every year issued by French Post (La Poste Française). They can only be used at UNESCO Headquarters in Paris.
Both stamps were issued in 2010, showing the Alpaca animal and the Alhambra Palace in Granada (Spain).
The Alhambra was originally a small fortress and was renovated and rebuilt in the 13th century by the emir of the ancient Emirate of Granada. After the conclusion of the Christian Reconquista in 1492, the site became the Royal Court of Ferdinand and Isabella (where Christopher Columbus received royal endorsement for his expedition), and the palaces were partially altered in the Renaissance Style. This site is inscribed at Unesco's since 1984.
