La Bandera de España, or the Flag of Spain, features three horizontal stripes: red, yellow, and red. The yellow stripe is twice the height of each red stripe. The flag's design symbolizes the country's rich history and cultural heritage. The current version was officially adopted in 1981, although variations have existed since the late 18th century. The flag often includes the Coat of Arms of Spain on the yellow stripe, which represents the various kingdoms that make up the nation. The colors red and yellow are believed to be inspired by the Spanish Empire and its historical significance.
