The Aqueducts in Malta and Gozo

Found in both Malta and Gozo, the Aqueducts' purpose was to transport water from a particular source to another destination. The Gozo Aqueducts were built by the British between 1839 and 1843 to supply the population with fresh water. Whereas The Wignacourt Aqueducts are a 17th-century structure, built by the Order of Saint John to carry water from the springs in Dingli and Rabat, to the newly-built capital city of Valletta.  

Fact: you can see a replica of the Aqueducts next to the Horizon Pool at Hilton Malta.
