Aldenham School is a co-educational independent school for pupils aged eleven to eighteen, located between Elstree and the village of Aldenham in Hertfordshire, England. There is also a preparatory school for pupils from the ages of five to eleven. It was founded in the late sixteenth century by Richard Platt. History The school was founded in 1597 by Richard Platt, owner of a City of London brewery and Master of the Worshipful Company of Brewers in 1576 and 1581. In 1596, Queen Elizabeth I granted him letters patent to build "the Free Grammar School and Almshouses" at Aldenham; the foundation stone was laid in 1597. Before Platt died in 1600 he obtained an endowment for the School by a covenant between himself and the Brewers' Company. It became a free village grammar school for young boys, also taking in private pupils. In the early 19th century an investigation by the Education Charities Commission of the Poor led to the Tudor Grammar School being demolished and replaced by two new schools: a lower school providing an elementary education for the local population, and a grammar school for fee paying boarders. In the late 1860s, the Platt estate in St Pancras, which provided the endowment of the school, was compulsorily purchased for the construction of the St Pancras railway station, and the Midland Railway had to pay compensation of £91,000, . In a measure described by the headmaster of the time as "a violent act of confiscation", the Endowed Schools Commissioners, acting under the Endowed Schools Act 1869, diverted more than half of this money to other schools. In their scheme approved in 1875, £20,000 went to the North London Collegiate School and Camden School for Girls, £13,333 6s 8d to support secondary education in Watford (see ), £10,000 to Russell Lane School, Southgate, and £8,000 to two elementary schools, Medburn School, Radlett, and Delrow School, Aldenham. The school expanded during the 20th century, and in the 1970s girls were admitted, thus paving the way for the school to become fully co-educational. A new Sixth Form Centre was opened in 2012 providing study and recreation facilities for Sixth Formers under one roof. In the summer of 2016, restorations were carried out on Beevor's and McGill's House, improving and updating the boarding facilities. Owing to the increasing number of girls in the school, in September 2017 Riding's House became a girls' day house.
