A porte-cochère (/ /; French: [pɔʁt.kɔ.ʃɛʁ], late 17th century, literally 'coach gateway'; plural: porte-cochères, portes-cochères) is a doorway to a building or courtyard, "often very grand," through which vehicles can enter from the street or a covered porch-like structure at a main or secondary entrance to a building through which originally a horse and carriage and today a motor vehicle can pass to provide arriving and departing occupants protection from the elements.
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. 
Portes-cochères, which are for vehicle passage, are often confused with porticos, columned porches or entries for human traffic.
The porte-cochère was a feature of many late 18th- and 19th-century mansions and public buildings. A well-known example is at Buckingham Palace in London. A portico at the White 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.
Today portes-cochères are found at both elaborate private homes and such public buildings as churches, hotels, health facilities, and schools. Portes-cochère differ from carports in that the vehicles pass through for passengers to board or exit rather than being parked beneath the covered area.
