The Andradas Fort (Portuguese: Forte dos Andradas, originally Portuguese: Forte do Monduba) is a fortification in the Morro do Monduba, at Guarujá, in the state of São Paulo in Brazil.[1]
The fort was constructed, along with the Itaipu Fortress (Portuguese: Fortaleza de Itaipu), in order to defend Santos bay and its port.[2] It was home to the 5th Independent Battery of Artillery of Coast (Portuguese: 5ª Bateria Independente de Artilharia de Costa).
Design
The fort hosts four Krupp guns, each with 280 millimetres (11 in),[2] 300 pounds (140 kg)[3] ammunition with a range of 12 kilometres (7.5 miles). An observatory post, with a telescope and a pair of telemeters, calculated distances and positions of the ships approaching the bay. Three underground arched tunnels, one 200 metres (660 ft) and two 50 metres (160 ft) long, connect the facilities together, as well as housing six ammunition depots and a power room (housing a 3-phase 139V generator), plus a kitchen, canteen and toilet facilities. It was designed so that most of the structure was underground and hidden behind an "invisible curtain" of trees.[2]
