Portas do Cerco is an area on the northern tip of the Macau Peninsula known by its border gate built in 1849, after a clash between China and Portugal over the death of Macau's governor Ferreira do Amaral. This small battle won for Portugal by Coronel Mesquita led to the extension of Macau northwards by the Portuguese. At the limit of said expansion the historic Portas do Cerco were built with the inscription "A pátria honrai, que a pátria vos contempla" (Portuguese for: "Honor your motherland, for your motherland looks over you") on the façade, and 1849 on its inner arch. For the next 155 years the gate would serve as the border between Macau and Canton.
