Andorra shares a border of 57 km and 64 km with these two countries. The Principality is especially known for the natural beauty of its 3 valleys, two of which date from the Ice Age, while the other was created by river erosion. The Principality covers an area of 467.7 km2. The climate is healthy.
Water is one of the most important natural resources of Andorra.
The richness of the flow of the Valira and Madriu rivers has allowed the use of hydroelectric energy since the 1930s. The concession granted in 1929 to develop this resource for generating electricity resulted in the construction of the country's main roads and made possible the installation of an electrical grid. The official language of Andorra is Catalan, but French and Spanish are widely used as well, owing to the economic and social links with France and Spain. These days Andorrans are increasingly using English for commercial purposes.
