Porte de Choisy

Porte de Choisy stands at the location of a former gateway that pierced the nineteenth century Thiers wall, the last great defensive fortification built around Paris. This massive structure of stone and earth was completed in 1844 to protect the city from invasion, but the military technology of the era quickly rendered it obsolete. By the early twentieth century, the wall was demolished, and its route became the path for the modern boulevard that circles the city today.
