King's College school was founded in 1969 and took its name from the University of London College. King's College is the name of various schools and university colleges in Britain, which are all independent, as is King's College, Madrid.
After occupying temporary premises for some nine years, the main school moved in 1978 to its present, purpose-built premises in the pleasant residential area of Soto de Viñuelas to the north of Madrid. The first section of the building was opened by the British Ambassador to Spain Sir Anthony Acland, KCVO, CMG. Since then, many improvements and additions have been made to the building and facilities including additional science laboratories, a purpose-built Early Learning Centre for children between the ages of two and three, an auditorium with seating capacity for 350 people and a Music School with six rooms for individual or small group tuition. Similarly, sports facilities have been enhanced with the construction of a 25 metre indoor swimming pool and an all-weather, floodlit multi-sports area. In September 2011, a brand new Boarding House opened in the school grounds offering excellent boarding facilities for pupils of Secondary age. Plans for future development include a covered sports hall.
Not only has there been sustained growth and improvement at the main school in Soto de Viñuelas, but the school's presence in other areas of northern Madrid has also increased significantly over the last few years. In September 2004, King's Infant School in Chamartín moved from its original premises with 75 pupils, to a brand new building catering for over 200 pupils. Three years later, in September 2007, King's College School opened its doors in La Moraleja catering for 500 pupils aged 3 to 14 years.
Ever since its foundation over forty years ago, King's College has grown in strength and prestige. This is reflected in a variety of ways including the steady increase in pupil numbers to over 2000 at present, the excellent academic results obtained every year and the entrance of senior pupils to the best universities in the world.
