Over here some of concrete ceiling has been removed. You can see a cross section of the construction if you look up. The area at the top was tightly packed with soil to soften the blast. If you look carefully around you will see crosses on the walls. This is where people would place their beds and carve a cross above themselves for protection. There is even one cross with a niche for a religious picture beneath it.
About thirty people could sleep here and when things got very busy over 100 people would cram into the shelter. Because this well was the largest in the area it was used as a chapel and people came in through the tunnels and a temporary wooden altar was set up.
The lamps you see on the wall would have been lit with kerosene. The air down here during air raids would have been very bad.
If you look around you can see different access points to the shelter. The others are all bricked off now but they used to connect to the hundreds of subterranean tunnels of Valletta. It is said that there are more streets under Valletta, than on the surface. Many of them are deliberately built with a zig-zag direction to prevent the blast of a bomb from going right through the tunnels.
