The Portas do Cerco is an area in Nossa Senhora de Fátima, Macau, China.

The Portuguese built the gate in 1849 to replace a crumbling wall that the Chinese erected during the Ming dynasty in 1573.

[3] It was the site of the Passaleão incident, a clash between the Qing dynasty and the Kingdom of Portugal in 1849 over the death of Macau's governor Ferreira do Amaral.

The Barrier Gate served as a de facto boundary, but the precise limits of Macau's border has never been formally demarcated.

The new Posto Fronteiriço das Portas do Cerco (Barrier Gate Border Post) was opened on 15 January 2004.
