of fashion as fortifications and residences. Many were destroyed in civil wars between the 17th and 18th centuries or incorporated into gardens as an alternative to follies. During the 19th century, keeps became fashionable once again and in England and France, a number were restored or redesigned by Gothic architects. Despite further damage to many French and Spanish keeps during the wars of the 20th century, keeps now form an important part of the tourist and heritage industry in Europe. Etymology and historiography Since the 16th century, the English word keep has commonly referred to large towers in castles. The word originates from around 1375 to 1376, coming from the Middle English term kype, meaning basket or cask, and was a term applied to the shell keep at Guînes, said to resemble a barrel. The term came to be used for other shell keeps by the 15th century. By the 17th century, the word keep lost its original reference to baskets or casks and was popularly assumed to have come from the Middle English word keep, meaning to hold or to protect. Early on, the use of the word keep became associated with the idea of a tower in a castle that would serve both as a fortified, high-status private residence and a refuge of last resort. The issue was complicated by the building of fortified Renaissance towers in Italy called tenazza that were used as defences of last resort and were also named after the Italian for to hold or to keep. By the 19th century, Victorian historians incorrectly concluded that the etymology of the words "keep" and tenazza were linked and that all keeps had fulfilled this military function. As a result of this evolution in meaning, the use of the term keep in historical analysis today can be problematic. Contemporary medieval writers used various terms for the buildings we would today call keeps. In Latin, they are variously described as turris, turris castri or magna turris – a tower, a castle tower, or a great tower. The 12th-century French came to term them a donjon, from the Latin dominarium "lordship", linking the keep and feudal authority. Similarly, medieval Spanish writers called the buildings torre del homenaje, or "tower of homage". In England, donjon turned into dungeon, which initially referred to a keep, rather than to a place of imprisonment. While the term remains in common academic use,
