Most individuals when passing by a structure that has white stucco walls, horseshoe arches, decorative ironwork and low pitched roofs covered in red tiles instantly associate it with Spanish Colonial, but it is so much more than these few elements.

To truly understand the Spanish Colonial Style one must travel back in time to Spain when it was under Moorish (Muslim) rule which occurred between 711 and 1492 AD. Towards the end of their rule, Moorish leaders built The Alhambra (The Red One) a palace/fortress located in Granada. The Alhambra is considered to be one of the world's greatest forms of Andalusian architecture. With its horseshoe arches, square towers, and extensive tile work one can see how it greatly influenced the early Spanish Colonial style.
In 1492 came of conquest of The Kingdom of Granada by Ferdinand and Isabella. Indeed it was within the walls of The Alhambra that Christopher Columbus was granted an audience with the royal couple which resulted in his discovery of America later that same year. After his heroic return to Spain came the extensive exploration and colonization of the United States by the Spanish.
With their arrival in the new world the Spanish brought with them their design ideals. Not having the same building materials available they began to look at the adobe structures built by the local people and combined the two styles which resulted in what we have now come to call Spanish Colonial. The oldest governmental building in America is the Palace of the Governors located in Santa Fe, New Mexico. Construction was begun on the Palace in 1610. It is one of the earliest examples of the style.
