 By 1167, with the construction of the medieval walls, the basilica was to be found within the city, at the new Porta Ticinese (Ticinese gate).The basilica of San Lorenzo remained throughout the Middle Ages a symbol of the legacy of the Roman Empire in Milan.Subsequently, during the age of the Renaissance, especially after the 1154 destruction of the other Ancient Roman structures by Emperor Barbarossa, the temple was an example of the classical architectural canons admired by humanists, and studied by architects and artists such as Bramante, Leonardo, and Giuliano da Sangallo.
