In 1993, the country's first constitution established a parliamentary democracy with executive, legislative, and judicial branches located in Andorra la Vella.",

A temple was constructed there by Phoceans, the temple of Hercules Monoikos (Monoikos means single house or single temple).",

Its written constitution was adopted on October 8, 1600. The tiny nation was recognized by Napoleon's France in 1797, and by the other European nations at the 1815 Congress of Vienna.",
