Brisbane is a small city located in the northern part of San Mateo County, California on the lower slopes of San Bruno Mountain. It is on the northeastern edge of South San Francisco, next to the San Francisco Bay and near the San Francisco International Airport. The population was 3,597 as of the 2000 census. Brisbane is called "The City of Stars" because of a holiday tradition established over 65 years ago. At the start of the Christmas/Hanukkah season, many residents and business owners place large, illuminated stars, some as big as 10 feet (3.0 m) or more in diameter, on the "downhill" sides of homes and offices throughout Brisbane. As Brisbane is built on the eastern slope of San Bruno Mountain, visitors and residents entering at night are treated to a star-studded mountain vista. Many of the stars are kept up all year.
