In medieval
castles the chemise (etym. fr. shirt) was typically a low wall encircling the
keep, protecting the base of the tower. An alternate term, more commonly used in English is
mantlet wall.In some cases, entry to the keep was only accessible from the chemise (i.e. at the first floor level). Numerous examples exist of highly varied form, including the heavily fortified chemise of
Château de Vincennes, or the more modest example at
Provins, both in
France. Some chemises are suggested to have been developed from earlier
motte and bailey defences, though they may not usuallly be referred to as chemise. In later
fortification, a chemise is a wall with which a
bastion or any other bulwark of earth, is lined; for its greater support and strength.
