[PAR] [TLE] Macau Peninsula [SEP] Macau Peninsula is the most populous and historic part of Macau.  It has an area of 8.5 km² (4 x ) and is geographically connected to Guangdong province, at the northeast, through an isthmus 200 m wide.  The peninsula, together with the city centre of Zhuhai, sits on an island separated from the continent by distributaries of the Pearl River.  The Border Gate (; Portuguese: "Portas do Cerco" ) was built on the northern isthmus.  At the south, the peninsula is connected to Taipa Island by three bridges, the Friendship Bridge ("Ponte de Amizade"); the Macau-Taipa Bridge ("Ponte Governador Nobre de Carvalho"); and the Sai Van Bridge ("Ponte de Sai Van").  The longest axis extends 4 km from the Border Gate to the southwestern edge, Barra (媽閣嘴).  There is a western Inner Harbour (內港), and an eastern Outer Harbour (外港).  The 93 m Guia Hill (松山) is the highest point on the peninsula, which is, on an average, 50 to .  Many coastal places are reclaimed from sea.  The Historic Centre of Macau, which is entirely in the Macau Peninsula, became a World Heritage Site in 2005. [PAR] [TLE] Portas do Cerco [SEP] The Portas do Cerco is an area in Nossa Senhora de Fátima, Macau, China.  Located on the northern tip of the Macau Peninsula, it is known by its border gate separating Macau from mainland China.  The gate was built in 1849 to replace a crumbling wall that was erected in 1573 to mark the border of the Portuguese colony.  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.  Led by Colonel Mesquita, Portugal won the small battle which led to the extension of Macau's border northwards.  At the limit of said expansion, the Portas do Cerco was 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 on its inner arch in 1849.  For the next 155 years, the gate served as the border between Macau and China.
