I would say this place is unfortunately reductively interesting. What diminishes its natural historical interest are the now perplexing plywood prop, staged and commercial aspects. There is inside a mix of American, Italian and German, NATO military artifacts from World War II all the way through the 1970s. There is a “command center” that is pure fiction as well as a plywood plastered bunker gunner (copy of the real ones you might find at Normandy beaches) inside the tunnel. You have to weed out the gems of historical fact amidst what feels like an army surplus hodgepodge or science fiction film set. No photos apparently allowed inside for unknown reasons as everything is over fifty years old and decommissioned.

As you’re leaving the tunnels, you are shuttled through a German style building built recently within one of the tunnels as a gift shop where they sell sweatshirts that read Bunker Sorrate in case you were confused about the theme park masquerading as history.

Frankly, the most interesting part of the entire visit was the free photography exhibition of historical photographs in the visitor’s center.

Your time on Sorrate is probably better spent hiking up to the top and enjoying the wonderful views over the Roman Campagna and worth checking out the various hermitages with frescos dating back to medieval times.
