Walter Pyramid

The Walter Pyramid is a pyramid-shaped indoor arena on the north campus of (CSULB) in , serving as the primary home for the university's men's and and teams. Opened on November 30, 1994, at a cost of approximately $22 million, it features a distinctive cobalt-blue exterior rising 18 stories high with a square base measuring 345 feet per side, making it one of only four pyramid-shaped buildings in the United States. Architecturally, the Walter Pyramid is recognized as the largest space-frame structure in North America, constructed using 18,000 steel tubes, 160,000 bolts, and connection modules that form its innovative pyramid design, which allows for cantilevered seating on moveable platforms and a 39,000-square-foot beechwood flooring adaptable for multiple sports. Its visibility from miles away has made it an iconic landmark for CSULB and the surrounding community, drawing nearly 200,000 visitors annually for athletic events, physical education classes, youth camps, and other gatherings. The arena has a capacity of 4,200, with the opening night drawing a crowd of 5,021 during a 71–64 men's basketball victory over the University of Detroit Mercy. Originally known as the Long Beach Pyramid, the facility was renamed the Walter Pyramid on March 5, 2005, in honor of philanthropists Dr. Mike and Arline Walter following their significant donation to the university. It has hosted prestigious events, including four NCAA Men's National Championships—the most recent in 2024—and the 2003 NCAA Women's Regional Semifinals and Finals, underscoring its role in collegiate athletics. As of November 2025, the arena remains a cornerstone of CSULB's athletic program; however, the CSU Board of Trustees considered renaming it the LBS Financial Pyramid as part of a proposed 12-year, $8.5 million sponsorship with LBS Financial during their November 17–19 meeting, with the outcome pending as of November 17.

History

Planning and construction

The planning and construction of the Walter Pyramid formed a key component of , Long Beach's campus expansion initiatives to bolster its athletic infrastructure in the early . Construction began with a ceremony in December 1992, marking the start of the project aimed at creating a multi-purpose arena for university sports. In 1992, Long Beach-based architect Don Gibbs was selected to lead the design, while the Nielson Construction Company of was contracted for the build. The total cost amounted to approximately $22 million (equivalent to about $48 million in 2025 dollars). This investment supported the development of a distinctive venue intended to serve as both a functional facility and a visual landmark for the campus. This design decision prioritized a bold, recognizable silhouette over conventional arena layouts, resulting in a mathematically precise structure measuring 345 feet per side at its base. However, the sloped profile introduced significant engineering hurdles, particularly in assembling the internal steel space-frame and affixing the exterior aluminum cladding. The framework comprised 500 tons of hot-dip galvanized fabricated tube steel and pipe, bolted together with 18,000 tubes and 160,000 connections to form North America's largest space-frame structure at the time. Key construction milestones unfolded over two years, with foundation work commencing shortly after the in early 1993, followed by the erection of the steel skeleton and progressive cladding installation. The structure reached in mid-1994, allowing for interior fit-out and completion ahead of its scheduled opening later that year. These phases highlighted the project's technical demands, yet ensured the pyramid's emergence as a durable, 18-story edifice clad in cobalt-blue aluminum sheets.

Opening and renaming

The Walter Pyramid officially opened on November 30, 1994, hosting its inaugural event—a men's game where Long Beach State defeated the of 71-64 in front of 5,021 spectators, with the matchup televised nationally on . This debut marked the arena's transition from construction to active use as the home for university athletics, drawing immediate attention for its distinctive pyramid shape and capacity to host large crowds. In the early years of operation, the facility encountered challenges related to its unique architecture, particularly in crowd management for high-attendance events and adapting to the pyramid's acoustics, which caused sound reverberations that complicated audio clarity during games. Staff and event coordinators worked to refine these aspects, ensuring smoother experiences as the venue became a staple for Long Beach State sports. On March 5, 2005, the arena was renamed the Walter Pyramid during a to honor Dr. Mike Walter, former of the College of Business Administration at CSULB and vice president at , and his wife Arline, for their $2.1 million donation supporting facility upgrades, athletic scholarships, and program enhancements. This gift, part of their broader toward the university, facilitated improvements like enhanced training areas and equipment. The renaming bolstered CSULB's branding as an institution reliant on private support for athletics infrastructure and fostered stronger donor relations in the mid-2000s, with the sparking over $5 million in additional contributions from their network to university programs.

Architecture and design

Exterior features

The Walter Pyramid's exterior embodies a precise geometric form, with each side of its square base measuring 345 feet (105.16 ) and the structure ascending 190 feet (57.91 ) to an apex equivalent in height to an 18-story building. This configuration establishes it as a mathematically true , a rare architectural feature that positions it as one of only four such buildings , alongside the Luxor Hotel in Las Vegas, Nevada; the Pyramid Arena in ; and the Pyramid in , . The pyramid's sloped surfaces are sheathed in dark-blue aluminum panels, creating a bold exterior that enhances its visual prominence against the Long Beach skyline. These panels were chosen for their aesthetic vibrancy and durability, offering resistance to and in the coastal while requiring minimal upkeep. Beneath the cladding lies a space-frame skeleton—believed to be North America's largest—composed of 18,000 galvanized tubes interlocked by more than 160,000 bolts to support the expansive, inclined planes. Positioned at 1250 Bellflower Boulevard on the campus, the pyramid harmonizes with its academic surroundings, where adjacent parking facilities like Lot G11 and the Pyramid Parking accommodate visitors, and networked pedestrian walkways facilitate direct access to its base.

Interior layout

The interior of the Walter Pyramid centers around a expansive arena floor measuring 39,000 square feet, constructed with sprung for durability and performance. This central space supports multi-purpose configurations, including setups for and through adjustable court markings, as well as conversions for concerts via movable staging elements. Surrounding the arena floor, the upper levels feature cantilevered platforms that serve as walkways and vantage points, taking advantage of the pyramid's sloping interior walls to ensure broad, unobstructed sightlines across the venue. These platforms, each weighing 81 tons, are hydraulically adjustable to facilitate flexible spatial arrangements for different activities. within this non-traditional is provided through elevators and ramps that connect levels, allowing navigation adapted to the inclined structure. Integrated into the interior slopes and space-frame structure are advanced lighting and acoustic systems. The lighting setup includes energy-efficient LED fixtures with programmable controls, enabling dynamic illumination for , events, and broadcasts at approximately 150 footcandles. Acoustically, the enclosed pyramidal space naturally amplifies sounds with echoing suitable for athletic competitions, but recent installations of Ai Series loudspeakers allow precise adjustments to mitigate reverberation for performances and presentations.

Facilities and capacity

Seating and configuration

The Walter Pyramid has a standard capacity of 4,200 fixed seats arranged around the main court for and events, with the ability to expand through additional floor seating or temporary stands. These retractable seating platforms, each weighing 81 tons, can be hydraulically raised to expose 39,000 square feet of activity floor space when needed for multi-court configurations or classes. The highest recorded attendance was 6,912, achieved on November 16, 2012, during a men's game against , utilizing expanded floor and standing-room options. Seating is organized in a lower bowl that fully surrounds the court for an intimate viewing experience, complemented by upper-level sections integrated along the pyramid's sloping walls. Premium options include courtside seats adjacent to the playing surface and club sections offering enhanced access and amenities. This layout ensures no seat is farther than approximately 200 feet from the action, maintaining visibility across the 345-foot-square base. For non-athletic events such as concerts, the arena supports adaptable end-stage configurations that typically reduce seated capacity to prioritize stage space but allow for up to 5,000 attendees with standing room on the floor. The overall capacity can nearly double the standard 4,200 through such arrangements, accommodating diverse event needs while preserving the venue's multi-purpose flexibility. Constructed in 1994, the Walter Pyramid includes safety and egress features designed to comply with California Building Code and standards of the time, such as multiple pathways and robust structural elements formed by 18,000 tubes and 160,000 bolts for rapid evacuation. These provisions ensure adherence to modern fire codes for assembly occupancies, supporting safe operations for crowds up to the maximum attendance levels.
