The last stage of Park 40 is probably the one that allows you to better understand the meaning of the coastal trench and the construction techniques adopted by the Austro-Hungarian army. It is on Mount Gurca, a karst mountain 370 metres a. s. l. (Mount Grisa is 35 metres lower) and is the highest point of Park 40.
Despite the dense vegetation that distinguishes this place today, you can guess that it was once an excellent vantage point of the entire Gulf during the war and, at the same time, a potentially exposed point for the Italian cannons firing towards it. For this reason, this stretch of the trench is very close to the ridge, as this would have made it more difficult to calculate the shot. As an additional precaution the trench follows a zigzagging path so in case a large-calibre projectile had fallen inside, the damage caused by an explosion would have been limited.
The redevelopment of this section has also allowed the recovery of what was probably a cannon post (on the left looking out to sea) while all around the area of 14X18 metres two underground positions connected by a walkway can be observed.
