Macau Maginot Line
Macau fortresses had suffered a constant updating required by the evolution of the artillery firepower. After the trenches system failure in W.W.I., the Maginot and Siegfried line were considered inexpugnable compounds.
In Guia Hill, formerly a military restrict area site, in 1930’s a Maginot type of low profile surface shape, well camouflaged system defense was built. Bunker’s, canons machineguns niches, ammunition depots, underground headquarter, shells elevators, etc.
In Taipa Island a similar system had started to build in order to create crossfire platforms. This static defensive system had a movable arm formed by ships and hydroplanes.
