Posto Fronteiriço das Portas do Cerco

The Posto Fronteiriço das Portas do Cerco (Portuguese for Frontier Post of the Border Gate) is an immigration and customs checkpoint in the Portas do Cerco area in northern Macao, on its border with mainland China's Zhuhai.

It is one of two border crossings between Macau and mainland China, the other being the Lotus Bridge between Macao's Cotai and mainland China's Hengqin Island. Travellers entering Macau pass through immigration and customs on the ground floor of the building, while those departing Macau pass through customs and immigration on the first floor. Its counterpart in Zhuhai is Gongbei Port, through which travellers must pass before or after Portas do Cerco.
