Historically, Collado Villalba was a rural town that gained prominence in the 19th and 20th centuries, especially with the advent of the railway connecting it to Madrid. Its history is intertwined with the development of the entire Sierra de Guadarrama region, and its transformation from a small agricultural community to a bustling suburban area has been marked by both modern expansion and the preservation of traditional customs.
Culturally, the town celebrates several local festivals and traditions, the most famous being the Fiesta de Santiago Apóstol in July, which includes traditional parades, music, and fireworks. Another notable celebration is the Virgen del Carmen festival, honoring the town’s patron saint with religious processions and local entertainment.
The town is known for its strong sense of community and has a rich blend of historical and modern influences. Its cultural fabric is influenced by nearby Madrid but also retains distinct local traditions, providing a vibrant mix for visitors to enjoy. Historical landmarks such as the Church of Santiago Apóstol and remnants of old agricultural life offer glimpses into its past.
