This coat of arms comes from Fonte da Batalha, in Porto, built around 1830 and demolished in the late 19th century.
It depicts the city’s former arms with the Virgin and the Infant Christ on her lap, flanked by two towers. A Royal Charter, which recognised the city for services rendered during the Peninsular War, added two arms to the traditional representation: one holding a flag bearing the royal arms and the other a laurel-encrusted sword.
