Porte-cochère

A Porte-Cochere is the architectural term for a porch or portico like structure, at the entrance to a building, through which it is possible for a horse and carriage or motor vehicle to pass, in order for the occupants to alight under cover and protected from the weather.

Porte-Cocheres were a feature of many late 18th century and 19th century mansions and public buildings. Well known examples are at Buckingham Palace in London and The White House in Washington.
