Bordeaux faced a similar problem with a submarine base. It is much bigger though: 450,000 sq ft. It is now a cultural center. According to my dad, who was involved in the conversion, working with 22 feet thick walls was very challenging.

- batou 11y agoThere's a bunker in the UK [1] that I went to. Before they could allow visitors they had to add a fire escape. Apparently it took a couple of days to cut a hole in the wall for this due to how strong it is and that was state of the art diamond cutting equipment. Good day out though.
