 The demolition of the grounds began in 1858 in the "Largo do Barão de S. Martinho", with the destruction of the Souto Gate, followed by the Eastern and São Bento Gates, still in the 19th century.After the beginning of the 20th century, many other lines of the castle were destroyed between the "Arco da Porta Nova" and "Rua dos Biscainhos", and from "Rua dos Biscainhos" and "Rua do Alcaide" (whose houses abutted the wall, between "Campo da Vinha" and "Praça do Município" and "Rua de São Marcos").Few remnants of the medieval lines remain today.
