How the Knights Built Valletta’s Underground 

When the Knights started building Valletta in 1566, they faced a problem. The city was on a peninsula with no natural springs. They needed a way to store lots of water, especially in case of a siege.

The solution? Carve out huge water tanks underground. The Knights used the limestone they dug up to build the city above.

The Underground Valletta complex includes several bell-shaped water cisterns. There’s also a massive reservoir that could hold over 3.6 million liters of water. That’s enough to fill more than 50,000 bathtubs.

The Knights made strict rules about water management. Every house had to have its own cistern to collect rainwater. They also had to have a separate tank for dirty water and waste. The goal was to keep the drinking water clean.

During the tour you will see some of the biggest reservoirs. You’ll be amazed by the size and the skill it took to create it.

Valletta’s Underground Shelters during WWII

During World War II, Valletta’s underground became a life-saver. With bombs hitting Malta, people sought shelter in the tunnels below.

At the war’s start, people connected spaces such as cisterns and tunnels to make a network of shelters. They also created multiple entrances. These were critical because the narrow streets risked being blocked by rubble from bombed buildings.

To dig the shelters, people used simple tools like pickaxes and shovels. The tunnels followed the same paths as the streets above, with names painted at intersections.

Living in shelters was tough. They were dark, damp, and crowded. However, people adapted. They used metal brackets to keep belongings off the wet floor.

Drawings of fighter planes on the walls reflect people’s interest in aerial battles. You can still see these drawings in the tunnels on the tour.

Today, walking through these tunnels, you can still see traces of those tough times. Bits of traditional Maltese tiles add colour to the cubicles.

You can also see prayer niches and religious figurines on shelter entrances. These are believed to ward off harm. This tradition endures among Maltese people today. As you walk, you’ll spot houses with statues of Saint Mary or Jesus adorned next to the doors.
