A buttress is a structure built against another structure in order to strengthen or support it. Historically, they have been used to strengthen large walls or buildings such as churches, but they continue to be used in large modern structures such as retaining walls and dams.
Buttresses that are used to counteract, or retain, the lateral force of water or earth may be referred to as counterforts.
See Flying buttress for more information.
