Definition of "Montanha"

Mong-chau, or Ballast island, bears N.N.W., distant 2 1/2 miles, from the west point of Montanha, and between them there are two passages leading to Macao, but both so shoal at low Avater as only to afford a passage for boats.

Macau will never be able to overcome its limitation posed by its tiny size, unless after 1999 the Central Government in Beijing would be generous enough, to make the adjacent islands D. João and Montanha part of the Macau SAR, which would increase the territory’s area at least three times.

Perhaps it would have been simpler if, like Taipa and Coloane, the Portuguese had physically merged Macau with two other islands: Montanha and Dom João (Xiao Hengqin and Da Hengqin, in Cantonese, with Montanha known as Tai Vong Cam). […] The most curious thing: this small, economically more valuable part corresponds almost entirely to the landfill that in the 90’s linked the two islands, which means that the original land of Montanha and Dom João was mostly hilly and unsuitable for real estate development (as the images in these pages show). […] For a short time, two years later, the Japanese expelled the Portuguese, and at the end of World War II, Montanha and Dom João passed definitively to the Chinese side (in 1938, a Portuguese-language newspaper published in Macau tells us that General Chiang-Kai Chek proposed a landfill connect the two islands . .).

It’s hard to imagine now, but there were once three mountainous, verdant islands between Macau and mainland China. The Portuguese named them Dom João, Montanha and Lapa. Later the islands became known in Chinese as Xiao (Little) Hengqin, Da (Big) Hengqin and Wanzai, respectively.The two Hengqins, which faced Coloane and Taipa, were eventually joined by land reclamation to form a single island while Wanzai, a mere few hundred metres from Macau’s Inner Harbour (Porto Interior), saw its inclines levelled enough to become a peninsula.
