Ta' Qali is a wide open space in the limits of Attard and Mosta in central and northern Malta respectively, which contains the national football stadium, the Malta Fairs & Conventions Centre, Ta' Qali National Park, a crafts village, and a national vegetable market which is locally known as the Pitkalija.
Shortly before World War II, the area was used to build a military aerodrome and a station for the Royal Air Force, which the British called RAF Ta Kali; Maltese place names were often corrupted in this fashion. RAF Ta Kali was operational throughout the war and continued to be used as an RAF airfield until the mid-1950s. Latterly, RAF squadrons based in the United Kingdom visited Ta Kali as part of their annual proficiency training.
