Dive into the heart of Downtown Los Angeles, tracing an forgotten conspiracy that threatened California's vital water supply in the early 20th century.

Step into the shoes of an investigative journalist, Lewis Bradbury, at the turn of the century, as Los Angeles undergoes dizzying transformations. Your mission is to unmask the dark forces attempting to undermine the colossal Los Angeles Aqueduct project, inaugurated in 1913. At each stage of this approximately 1.5 km journey, lasting about 135 minutes, open your phone: augmented reality archival documents appear on Art Deco facades, old maps overlay historical squares, and virtual witnesses whisper clues on the cobblestones. From the imposing Union Station, a 1939 masterpiece, to the historic alleys of El Pueblo, each site holds a piece of the puzzle. More than an outdoor escape game: an interactive tour immersed in the history of Los Angeles, with anecdotes revealed at each stop and confidential sites that classic guides often miss.

The story that haunts this land

Your investigation begins at Union Station, this unified Los Angeles railway station, inaugurated on May 1, 1939. Designed by John Parkinson and Donald B. Parkinson in a Beaux-Arts and Art Deco style, it replaced five distinct stations, symbolizing the unification of a rapidly expanding city. This 141-meter long and 87-meter wide building, with its 135-foot high central hall, was at its peak a daily passage point for 100,000 passengers. It is here, among the bustling travelers and city rumors, that you seek the first clues of a secret network opposing the great aqueduct project.

Continue towards El Pueblo de Los Angeles Historical Monument, the historic heart of Los Angeles, founded in 1781 by Governor Felipe de Neve. On the original 44 acres of the pueblo, you discover structures like the Iglesia de Nuestra Señora la Reina de los Ángeles, built between 1818 and 1822, the oldest continuously used religious structure. The Pico House, dating from 1869, with its 3-foot thick adobe walls, testifies to the wealth of the era. Olvera Street, restored in 1930, is the oldest street in Los Angeles. These history-infused places reveal the initial tensions surrounding water, essential for the survival of this pueblo since its founding on the banks of the Los Angeles River.

Your path then leads you to the Los Angeles State Historic Park, established in 1971, which spans 13 hectares along the Los Angeles River. This park houses the ruins of the Sepulveda House (1887), a Victorian mansion partially destroyed by the 1914 floods. The Gálvez House, built around 1887, illustrates 19th-century residential architecture. The site also preserves the remains of the Tongva settlement, an indigenous people predating the 18th century, and records of major floods in 1914, 1938, and 1961. It is here, by this capricious river, that you understand the urgency of securing water supply for Los Angeles' growth and the challenges of 19th-century urban heritage in Los Angeles.

The route takes you to the Bradbury Building, a structure designed in 1893 by George Herbert Wyman, commissioned by Lewis Bradbury. This 5-story building is an architectural marvel, with its 60-foot high interior courtyard and its iron and glass skylight. It was one of the first extensive uses of structural steel in Southern California, and its hydraulic elevators are original. Almost demolished in 1970, it was saved by preservationists. In this gem of Beaux-Arts California Architecture, listed on the National Register of Historic Places, the shadows of conspirators still seem to linger. Here you decipher coded messages, hidden in the ornamental details, guiding you to the heart of the plot.

Your quest concludes at the Millennium Biltmore Hotel Los Angeles, opened on October 3, 1923, an 11-story, 683-room landmark designed by Schultze & Weaver in a Beaux-Arts style. Having hosted 8 Oscar ceremonies and the first televised Oscar broadcast in 1953, this venue is a privileged witness to Los Angeles history. It is in its lounges, beneath its gilded ornamentation, that you piece together the entire Los Angeles aquatic conspiracy and understand the motivations of those who tried to control the history of the Los Angeles River. This thematic circuit in California will have shown you how the quest for water shaped the destiny of a city, from its foundations to its role as a global metropolis.
