The Hollywood Dell is a residential neighborhood in the Hollywood Hills, which gets it's name because it sits "in" the hills rather than atop them. Its borders are generally defined as east of Cahuenga Boulevard, north of Franklin Avenue, west of Argyle Avenue, and south of the Hollywood Reservoir. The Krotona Institute of Theosophy was founded in Hollywood in 1912 by Albert P. Warrington. Its headquarters, including Krotona Court (1912) and the Grand Temple of the Rosy Cross (1914), were located along Primrose Avenue and Vista Del Mar Avenue, which operated there until 1926. Residential development in the Dell dates back to the early 1920s. However, some structures like the Hollywood Dell Dairy Farm at 6403 Primrose Avenue date back as far as 1914. The neighborhood is famous for its Spanish Colonial Revival architecture. Other common styles from the 1920s and 1930s include: Mediterranean Revival, French Normandy, English Tudor, American Craftsman and Storybrook Style. The area's proximity to movie studios made it a popular enclave for the early film industry.
