It is symmetrically positioned in the front line of the defence artillery zone of Magadino Superiore (see the article). As a matter of fact, the Swiss military forces built in the Valle Verzasca a series of corresponding forts and bunkers just before the beginning of the First World War. The idea behind the defence elements was to block any possible route from the South (Lake Maggiore) leading to Bellinzona and further to the North to the massive of Sankt Gotthard.
It is the most easily accessible work which is a sort of the long fort, coloured in red, appropriately named today La Casa Rossa (in English: the red house), and situated above the village of Gordola. It is an infantry barrack built on the top of the hill, from where opens a spectacular view on the northern part of Lake Maggiore and Gambarogno. The number of canons originally installed is unknown till today.
From the northern side, there is also an artillery fort built on the rock in 1913 which had the same layout of the one in Magadino Superiore which was conceived for approx. 70 soldiers. Originally, there should have been four canons of 7.5 cm firing toward Magadino, two headlights and at least two emplacements for heavy machine guns. The fort was somehow upgraded in 1941 as there has been since that date situated on the top of the Eastern entrance.
Further to the South, alongside the rail bridge, there are also two bunkers and one trench line.
