Câmpia Turzii is a city in Cluj county, Romania, which was formed in 1925 by the union of two villages: "Ghiriş" (Hungarian: Aranyosgyéres) and "Sâncrai" (Hungarian: Szentkirály).
The village of Sâncrai was mentioneed in a 1219 document as "villa Sancti Regis" ("village of Holy King"), while Ghiriş was first documented in 1292 as "Terra Gerusteleke" ("Gerusteleke", literally meaning "plot of Gerus" in Hungarian).
Michael the Brave was murdered by agents of Giorgio Basta at the current location of Câmpia Turzii on August 9, 1601.
The city is home to the Romanian Air Force's RoAF 71st Air Base, and during the NATO Summit of 2008, the 323rd Air Expeditionary Wing of the United States Air Force. F-15s from RAF Lakenheath in the United Kingdom flew out during the summit to augment air defence forces for the event.
