The Candlestick Auditorium is the historic site of the signing of the Articles of the Federation on 12 August 2161 in San Francisco on Earth. At the time, the auditorium had been newly renovated. (ENT novel: Last Full Measure)
The auditorium was originally a sports stadium that was known as Candlestick Park. Built in 1960, the original stadium served as the home of the San Francisco Giants baseball team until 1999, as well as the San Francisco 49ers football team until 2013. The stadium was also noted as the site of The Beatles' final full concert in 1966. Torn down in 2014, the stadium was eventually re-built as an auditorium that featured prominently in early Federation history. (Historical accounts, ENT novel: To Brave the Storm)
Candlestick Park had a reputation for being cold and drafty soon after opening, and even with state of the art environmental systems, Candlestick Auditorium still had such problems in the mid 22nd century.
