Around two weeks ago, a Knights-era reservoir was discovered in Valletta, after Professor Ruben Paul Borg came across two dangerous openings near the St Andrew’s ditch.

Soon after the discovery was made, Prof Borg called reservoirs expert Steven Mallia to check it out.

Steven put a camera through the openings, thus confirming Prof Borg’s suspicions – an enormous reservoir from the time of the Knights of St John was right beneath their feet!

This reservoir can hold up to a million-and-a-half litres of water, and whilst that’s extremely big for a Maltese reservoir, it still isn’t the biggest one in Valletta. An old reservoir in the Fort of St Elmo holds the top spot.

A week after the discovery was made, Steven and historical vlogger Conrad Neil Gatt visited the spot to acquire new footage.

Said footage clearly shows the contents of the newly discovered reservoir, consisting of two chambers.

Unfortunately, one of the chambers is completely buried in with materials that were commonly found in shelters during the Second World War.

This goes that show that reservoir has been closed off since then.
