The municipality of San Agustín de Guadalix (8,832 inhabitants in 2006) is located 34 km north of Madrid.

Already settled by the Ibers, the village was conquered by Caius Flaminius' troops. During the Reconquest, most villagers were enrolled in 877 by Mohamed I, Emir of Córdoba, to fight the Christians. In 932, the Christian crossed Somosierra and Guadarrama and expelled the Moors. After this campaign, San Agustín remained a no man's land located between the two armies in conflict. In 1084, King Alfonso VI seized San Agustín on his way against Toledo and resettled the area with Castilians. In 1382, King Juan I transferred the village and domain of Agustín to Pedro González de Mendoza. The family kept them until 1461 when another Pedro González de Mendoza, Bishop of Calahorra and son of the famous poet Marques de Santillana, swapped it for other doamins with Diego Arias de Ávila, the "Finance Minister" (Contador mayor) of King Enrique IV. His descendants were the Counts of Puñonrostro, whose coat of arms is used today as the municipal arms of San Agustín. In the XVIth century, Queen Juana la Loca (Joan the Mad) granted to San Agustín the title of town "authorized to use gallows, spear, block, chain, whip and other signs and tools of jurisdiction and justice." The northern part of Valdelagua was incorporated into the town.
