Idora Park was a 17.5-acre (71,000 m2) Victorian era trolley park in north Oakland, California constructed in 1904 on the site of an informal park setting called Ayala Park on the north banks of Temescal Creek. It was leased by the Ingersoll Pleasure and Amusement Park Company that ran several Eastern pleasure parks. What began as a pleasure ground in a rural setting for Sunday picnics evolved into a complete amusement park visited by many residents of the San Francisco Bay Area. Its popularity declined after the advent of the automobile, and it was closed and demolished in 1929.
