Tres Cantos

Originally belonging to Colmenar Viejo, it seceded from the latter municipality in 1991, becoming the youngest municipality in the region. The urbanised area was conceived as a "satellite city" of Madrid developed by urban planners in the 1970s. It has a population of 48 326 inhabitants in 2020.The city, as other planned cities, has a distinctive structure. It consists of three phases and a newer development "Nuevo Tres Cantos". The two first phases are subdivided in sectors. Most sectors, especially in the first phase , include internally pedestrian public spaces, being surrounded by streets. The names of urban places are usually related to the sector in which they are located–for example, the Sector Océanos consists of five streets named after the five oceans.
