The Boulevard Beaumarchais is a boulevard of the 3rd, 4th and 11th arrondissement of Paris[1] and the longest of the Grands Boulevards.[2][3] The boulevard is around 700 meters long[4] and 35 meters wide.[2] It was originally named the Boulevard Saint-Antoine but had its name changed in 1831 to honor Pierre-Augustin Caron de Beaumarchais,[5] whose mansion was built on the boulevard in 1780.[6] The mansion was later seized by the government[7] and demolished in 1818[6] in order to expand the Canal Saint-Martin.[8] The boulevard was renovated in the 1980s.[2]
