Aporte-cochère (/ˌpɔːrtkoʊˈʃɛr/;French:[pɔʁt.kɔ.ʃɛʁ];lit. 'coach gateway';[1]pl. porte-cochères –pl. portes-cochères)[2] is adoorway to a building orcourtyard, "often very grand," through which vehicles can enter from the street[3] or a coveredporch-like structure at a main or secondary entrance to a building through which originally ahorse and carriage and today a motor vehicle can pass to provide arriving and departing occupants protection from the elements.[4][5]
Portes-cochères are still found on such structures as major public buildings and hotels, providing covered access for visitors and guests arriving by motorized transport.[6]
A porte-cochère, a structure for vehicle passage, is to be distinguished from aportico, a columned porch or entry for human, rather than vehicular, traffic.
The porte-cochère was a feature of many late 18th- and 19th-centurymansions and public buildings. A well-known example is atBuckingham Palace in London. Aportico at theWhite House in Washington, D.C. is often confused with a porte-cochère, where a raised vehicle ramp gives an architectural portico the functionality of the latter.[7]
Today portes-cochères are found at both elaborate private homes and such public buildings as churches, hotels, health facilities, and schools. Portes-cochère differ fromcarports in that the vehicles pass through for passengers to board or exit rather than being parked beneath the covered area.
Guard stones are often found at the foot of portes-cochère, acting asprotective bollards to prevent vehicles from damaging the structure.
