The Rothschild dynasty was founded by Mayer Amschel in Vienna in the 1760s. The founder's five sons established a vast European banking network. The family introduced an architectural style known as historicism, merging various historic and regional influences and expressing the European universality which was the family's stock in trade.
	The Château des Fontaines is a remarkable example of the Rothschild style. Its main façade pays tribute to King Henri IV's Place des Vosges and Place Dauphine in Paris. The pointed cylindrical towers add a medieval touch. The central section of the main building is inspired by the British and Dutch styles of the Northern Renaissance.
	Baron James-Edouard de Rothschild acquired the property in 1878. He was well-versed antiquarian and a passionate lover of books, and moved in the most erudite circles. He began work on the Château, but did not live to see it finished, dying in 1881 at the age of 37. His widow, the "Baroness James" completed the estate in 1892 and passed it on to her son Henri in 1895.
	Jesuit monks occupied Les Fontaines from the 1950s onwards. They built a chapel, a vast library and living quarters open to researchers from all horizons. They organised colloquiums on a great diversity of subjects.
	At the dawn of the 21st Century, CapGemini chose the site to build its Campus, thus perpetuating its vocation as a place of knowledge and international exchange.
