1926: Allied Architects shell
The first permanent shell was designed in 1926 by the Allied Architects of Los Angeles, a consortium formed to design public structures. The amphitheatre seating arrangement was designed by Myron Hunt, the Pasadena architect.
The 1926 shell featured decorative murals of sailing ships and Eastern imagery. It was immediately deemed unsatisfactory — both acoustically (the regrading of the hillside had degraded the natural acoustics) and visually (it was considered unfashionable). It did, however, provide increased seating capacity. The all-time attendance record was set in 1936, when 26,410 people crowded into the Bowl to hear opera singer Lily Pons.
1927: Lloyd Wright's pyramidal shell
For the 1927 season, Lloyd Wright was commissioned to design a replacement shell for a performance of the operetta Robin Hood. Working with leftover lumber from his film set for Paramount's Robin Hood (1922), Wright built a pyramidal shell with a design influenced by Southwest Indigenous and Mayan architecture.
The shell was built in 10 days for $1,500. Acoustically, it was superb — it "restored the original acoustical properties of the site" (according to Wright's son, Eric Lloyd Wright). No amplification was needed; lighting was hidden at the rear of the structure.
But the conservative Hollywood Bowl Association board members found the design too avant-garde — "too modern" or even "ugly." It was demolished at the end of the season.
1928: Lloyd Wright's concentric-arc shell
For the 1928 season, Wright was asked to design a circular version, though he warned that projecting sound properly would be problematic without his preferred pyramidal geometry.
His solution was a one-quarter elliptical shell composed of nine wooden panels arranged in concentric 120-degree arcs, covering a 120-degree arc total. The panels could be angled to "tune" the acoustics for different performances. The shell cost $6,000 and was designed to be easily dismantled and stored between concert seasons to protect it from winter weather.
This shell was acoustically superb — possibly the best in the Bowl's history. It looked great and functioned perfectly.
Unfortunately, the penny-pinching Hollywood Bowl Association refused to spend the $500 necessary to dismantle and store the shell over the winter, ignoring Wright's instructions. The shell was left exposed to the elements and destroyed by water damage. It had to be bulldozed the following spring.
1929–2003: Allied Architects shell (the iconic shell)
In a matter of three months in spring 1929, the Allied Architects (engineering by the firm of Elliot, Bowen, and Waltz) designed a permanent semi-circular shell made of transite (a mix of asbestos and concrete) over a metal frame. The structure weighed 55 tonnes.
The stage measured 90ft wide by 60ft deep; the shell rose 45ft high at its centre. The design featured clean white semicircular concentric arches — a simplified, permanent version of Lloyd Wright's 1928 shell.
Acoustically, it was inferior to both of Wright's shells, ranking only third-best in the Bowl's history. But it was deemed satisfactory at first, and its clean lines and white finish became iconic. This was the shell that defined the Hollywood Bowl in the public imagination for 74 years — the shell copied for music shells elsewhere, the shell that appeared in countless photographs, films, and television programmes. This is the shell that we have modelled.
Over time, the transite skin hardened, and the acoustics deteriorated. By the late 1970s, the Hollywood Bowl had become an acoustic liability. Various remedies were attempted:
- 1970s: Frank Gehry designed "sonotubes" — long cardboard cylinders suspended from the shell's ceiling to diffuse sound and prevent the orchestra's sound from dissipating
- Early 1980s: The cardboard tubes were replaced by large fiberglass spheres, also designed by Gehry
Neither intervention fully solved the problem. Musicians complained they couldn't hear the conductor. One engineer later admitted, "the conductor would say 'louder' and a guy on a recording mixing board turned up the volume on the French horns or whatever instrument, so the audience was getting a second-hand interpretation."
Preservationists fiercely opposed demolishing the 1929 shell, citing its storied history. But by 2000, consensus emerged that replacement was necessary. On 12 September 2000, the Los Angeles County Board of Supervisors voted unanimously to demolish the shell and replace it with a new, acoustically improved structure.
2004–present: Hodgetts + Fung shell (current shell)
Following a design competition in 1997, Los Angeles County and the Los Angeles Philharmonic Association hired Hodgetts + Fung (architects Craig Hodgetts and Hsin-Ming Fung) to lead a $25 million renovation.
Structural engineering was provided by Arup (Los Angeles office). Acoustical design was by Jaffe Holden Acoustics. The original 1929 shell was demolished in 2003 after preservationist lawsuits were settled. Construction took place in 2003–04. The new shell debuted in the 2004 summer season.
The design challenge was formidable: create a shell that was 30% larger than its predecessor, acoustically superior, visually reminiscent of the beloved 1929 shell, and flexible enough to accommodate both unamplified classical concerts and amplified rock shows with complex lighting requirements.
Hodgetts + Fung's solution synthesised elements from the Bowl's architectural history:
- The prominent front arch of the 1926 Allied Architects shell
- The broad profile of Lloyd Wright's 1928 shell
- The unadorned white finish and general lines of the 1929 Allied Architects shell
- A ring-shaped structure hung within the shell (echoing a similar structure in Lloyd Wright's 1927 shell), supporting lights and acoustic clouds
The most visible innovation is the 14.5-tonne aluminum acoustic canopy, commonly called the "halo" — an elliptical ring that appears to float above the stage. Designed by Jaffe Holden Acoustics, it solves acoustical problems while allowing the architects to maintain the shell's iconic visual profile.
Additional features include:
- 50ft diameter turntable built into the stage for rapid set changes
- Larger dressing rooms and staging areas in the wings
- Retractable screen to shade performers from the sun during afternoon rehearsals
- Four new video screens and towers for live camera feeds
During the 2004 season, the sound steadily improved as engineers learned to work with the shell's live acoustics. The current sound reinforcement system uses a line-array configuration of multiple loudspeaker enclosures hung vertically in a curved manner.
The shell has been widely praised as an architectural and acoustic success.
The Bowl as civic institution
The Hollywood Bowl is more than a performance venue. It is a civic institution woven into the fabric of Los Angeles life.
Since 1922, it has remained remarkably accessible. To this day, $1 buys a seat at the top of the Bowl for many classical and jazz performances — a legacy of the founding principle articulated by F.W. Blanchard: "popular prices will prevail."
Many of the key figures in the Bowl's founding were women, most notably the pianist Artie Mason Carter, whose connections with Los Angeles arts patrons were vital in the early years.
The Bowl has hosted everyone from Billie Holiday to The Beatles to Yo-Yo Ma. It has presented everything from opera (Carmen, Aida, Lohengrin) to ballet (Elysia, 1932 Olympics celebration) to jazz festivals to rock concerts. In recent years, film concerts — live orchestral performances accompanying screenings of classic films — have become a major part of the programme.
In November 2025, the Los Angeles Philharmonic named the concert stage the John Williams Stage — the first time in the Bowl's 103-year history that the stage has been named after anyone, honouring the composer's eight-decade relationship with the orchestra and the venue.
The Bowl was listed on the National Register of Historic Places in December 2023 — the culmination of decades of advocacy and investment by Los Angeles County and the Los Angeles Philharmonic Association.
Model-maker's lens
The Hollywood Bowl is one of those subjects where the icon is so familiar that the challenge becomes: how do you capture the essence without it becoming a cliché?
- Focus — the Allied Architects 1929 shell showing the bandshell from the audience's perspective with the concentric white arches. This is the view that has defined the Bowl for a century.
- Detail — the concentric arcs are the defining form. At model scale, we cannot replicate every structural nuance, but we can capture the rhythm of repetition, the sense of geometry radiating outward from the stage, and the contrast between the white shell and the shadowed interior.
- How it reads at small scale — extremely well, because the architecture is fundamentally simple: a series of arches; a stage. Simplified, it becomes even more iconic.
- How to display — best viewed head-on, as the audience sees it. The shell is designed to be read from a single primary viewpoint. Natural or warm lighting works well, emphasising the shell's curves and the play of shadow within the arches.
Modelling the Hollywood Bowl is an exercise in understanding architectural iconography. The shell has been refined over a century to become a symbol — of Los Angeles, of summer, of music under the stars. The model captures that Allied Architects 1929 shell design.

Frequently asked questions about the Hollywood Bowl
Who designed the Hollywood Bowl?
The site and amphitheatre seating were designed by Myron Hunt (1926). The iconic bandshells were designed by Lloyd Wright (1927, 1928) and Allied Architects (1926, 1929). The current shell (2004) was designed by Hodgetts + Fung with Arup and Jaffe Holden Acoustics.
When did the Hollywood Bowl open?
The Bowl officially opened on 11 July 1922, though performances on the site began in 1921.
Who was Lloyd Wright?
Lloyd Wright (Frank Lloyd Wright Jr., 1890–1978) was the eldest son of Frank Lloyd Wright. He was a landscape architect and architect active primarily in Los Angeles and Southern California. His two Hollywood Bowl shells (1927, 1928) were acoustically superior to all others in the Bowl's history.
Why was Lloyd Wright's 1928 shell destroyed?
Wright designed it to be dismantled and stored over winter. The Hollywood Bowl Association refused to pay the $500 cost to dismantle it. The shell was left exposed to winter weather and destroyed by water damage.
When was the current shell built?
The current shell was designed in 1997, built in 2003–04, and opened for the 2004 summer season.
What is the "halo"?
The "halo" is a 14.5-tonne aluminum acoustic canopy — an elliptical ring suspended over the stage — designed by Jaffe Holden Acoustics to improve sound projection while preserving the shell's visual character.
How many people does the Hollywood Bowl seat?
Nearly 18,000 — making it one of the largest natural amphitheatres in the world.
Is the Hollywood Bowl still in use?
Yes. It remains the summer home of the Los Angeles Philharmonic and hosts hundreds of concerts each year.
