The 2,400-bench-seat pavilion, dedicated in 1915 by sugar magnates John D. and Adolph B. Spreckels, holds the 4,518-pipe Spreckels Organ, the largest outdoor pipe organ in the world. You can hear this impressive instrument at one of the year-round, free, 2 pm Sunday concerts, regularly performed by civic organist Carol Williams and guest artists—a highlight of a visit to Balboa Park. On Monday evenings from late June to mid-August, internationally renowned organists
play evening concerts. At Christmastime the park's Christmas tree and life-size Nativity display turn the pavilion into a seasonal wonderland.
