Prayerbook Cross, Stone monument in Golden Gate Park, United States.

The Prayer Book Cross is a Celtic cross of blue sandstone from Colusa County, standing 57 feet high on an 18-foot-square stone pedestal seven feet tall. It is assembled from 68 pieces weighing 600,000 pounds, with each of the four arms made of eight pieces of 24,000 pounds. It stands in Golden Gate Park near Rainbow Falls.

The cross was paid for by George William Childs, a Philadelphia publisher, and dedicated on January 1, 1894, at the opening of the Midwinter Fair; construction had begun on November 4, 1892. It marks the Protestant service Francis Fletcher, Drake's chaplain, held near Drakes Bay around June 24, 1579, and the first use of the Book of Common Prayer in what became the United States. The original plan placed it near the Point Reyes Lighthouse.

The back inscription names three "firsts": the first Christian service in English on this coast, the first use of the Book of Common Prayer in the country, and one of the first recorded missionary prayers on the continent, closing with "Soli Deo Sit Semper Gloria." Episcopal services and pilgrimages were held at the cross in many years, among them 1906, 1931 and 1951.

The cross can be reached by walking paths from John F. Kennedy Drive, located east of Cross Over Drive in the park. The route involves some uphill walking, so comfortable shoes are recommended.

The structure is assembled from 68 individual stone pieces that together weigh about 600,000 pounds. Each of the four arms was constructed from eight separate pieces to achieve this massive scale.
