In 1987, Kelsang Gyatso entered a 3-year retreat at Tharpaland International Retreat Centre in Dumfries, Scotland. During his retreat, he wrote five books and established the foundations of the NKT-IKBU. After completing his retreat in the early months of 1991, Kelsang Gyatso announced the creation of the NKT-IKBU, an event which was celebrated by his students in the NKT-IKBU magazine "Full Moon" as "a wonderful development in the history of the Buddhadharma." Since that time, the NKT-IKBU has grown to comprise 1,300 centres worldwide, most principally study and meditation centers, some principally retreat centers, and four traditional-style Temples for World Peace. The Kadampa Web site stated that three more temples were soon to appear.
