The Rose Garden Arena, Portland’s premier indoor entertainment venue, has been a significant part of the city’s landscape since its inception. But when was this iconic structure built? Let’s delve into the history of this beloved arena.
Before we dive into the construction timeline, it’s essential to understand that the Rose Garden Arena has undergone several name changes and renovations throughout its existence. Initially known as the Memorial Coliseum, it was built to honor the veterans of World War II, the Korean War, and the Vietnam War.

The Inception of the Memorial Coliseum
The groundbreaking for the Memorial Coliseum took place on February 27, 1968. The construction was a collaborative effort between the city of Portland and Multnomah County, with the architectural firm Skidmore, Owings & Merrill (SOM) designing the structure.
The Coliseum was designed to be a multi-purpose arena, capable of hosting a wide range of events, from sports games to concerts and conventions. It was also intended to serve as a memorial to the veterans, with a reflecting pool and a wall of remembrance initially planned for the exterior.
The Construction Process
The construction of the Memorial Coliseum began in earnest in 1968. The arena was built using a combination of traditional construction methods and innovative design elements. For instance, the Coliseum was one of the first arenas to feature a retractable seating system, allowing for flexible event configurations.
The arena’s distinctive roof, a series of parabolic arches, was also a notable feature. These arches not only provided structural support but also created a unique aesthetic that would become a symbol of the arena.

The Opening and Early Years
The Memorial Coliseum officially opened its doors on October 12, 1969. The inaugural event was a Portland Buckaroos basketball game, which attracted a sell-out crowd of over 12,000 spectators. The arena quickly became a hub for sports and entertainment in Portland, hosting a variety of events throughout the 1970s and 1980s.
However, as the years passed, the arena began to show signs of age. In response, the city of Portland and Multnomah County launched a major renovation project in the late 1990s, which would transform the Memorial Coliseum into the Rose Garden Arena we know today.
The Transformation into the Rose Garden Arena
The renovation of the Memorial Coliseum began in 1998 and was completed in 2002. The project involved a complete overhaul of the arena’s interior, including the installation of new seating, the creation of luxury suites, and the addition of a state-of-the-art sound and lighting system.

The exterior of the arena was also updated, with the addition of a new entrance plaza and the installation of a large, illuminated rose sculpture, a nod to Portland’s nickname, the City of Roses. The arena was renamed the Rose Garden Arena to reflect these changes and its new identity.
The Rose Garden Arena Today
Today, the Rose Garden Arena stands as a testament to Portland’s rich history and its commitment to providing world-class entertainment. The arena has hosted a wide range of events, from NBA games to concerts by some of the world’s biggest musical acts.
Despite its many renovations, the Rose Garden Arena remains a beloved Portland landmark, its distinctive roof still a familiar sight on the city’s skyline. It’s a reminder of Portland’s past and a symbol of its vibrant present.
So, the next time you’re enjoying an event at the Rose Garden Arena, take a moment to appreciate the history of this iconic venue. From its inception as the Memorial Coliseum to its transformation into the Rose Garden Arena, this arena has been a part of Portland’s story for over five decades, and it continues to play a vital role in the city’s cultural landscape.
