Point Pinole is located in the city of Richmond, California. It is on the site of a number of former explosives factories; the largest of these was operated by the Giant Powder Company, which was relocated to this relatively remote spot following accidental explosions at its former sites in San Francisco and at Albany Hill. Giant had built the first dynamite manufacturing plant in the United States at a site known as Glen Canyon Park, which started up on March 19, 1868. On November 26, 1869, there was an explosion that destroyed every building on the site (including the fence around the plant). The plant was forced to move farther away from heavily populated areas. Another explosion occurred at the Albany Hill plant in 1892, before Giant built its last plant in the lightly populated area of Pinole Point. Giant created a small unincorporated community, which it named Giant, California. Later, the Giant community became the established Croatian community of Sobrante.
