The PGA European Tour is an organisation which operates the three leading men's professional golf tours in Europe: the elite European Tour, the European Senior Tour and the developmental Challenge Tour. Its headquarters are at Wentworth Club in Virginia Water, Surrey, England. The European Tour is the primary golf tour in Europe. The European Tour was established by the British-based Professional Golfers' Association, and responsibility was transferred to an independent PGA European Tour organisation in 1984. Most events on the PGA European Tour's three tours are held in Europe, but in recent years an increasing number have been held in other parts of the world outside Europe; in 2015 a majority of the ranking events on the European Tour were held outside Europe, though this included both Majors and World Golf Championship events that are ranking events for multiple tours.
