Construction is believed to have begun in 1390 by orders of
Henry II of Castile, and construction proceeded for fifty years under his son,
John I of Castile. It was sited where an old chapel stood. Supposedly he was spurred to this project due to his plundering of a
chartreuse during a campaign in France. This was the first chartreuse in Castille and Leon. In 1403, a small adjacent palace was built under Rodrigo Alonso. Multiple architects contributed to the complex, including
Juan Guas,
Rodrigo Gil de Hontañón,
Francisco Hurtado and
Vicente Acero. The refectory was designed in a
Moorish style. . The monastery was dissolved in 1835, and not till 1876 was some state protection afforded to the site. Since 1954, part of the monastery is occupied by the
Benedictine order; while part was a private luxury hotel, operating as the Sheraton Santa Maria de El Paular, for many years, until it closed in 2014. ==Design==
