Seattle Finally Gets Its NHL Team and a Revamped Arena

Coliseum - Washington State pavilion at Expo 1962

Fifty-six years on, “Paul’s Paraboloid”—otherwise known as KeyArena and formerly known as the Coliseum—is going to be reborn as a shelter for Seattle’s own, brand-new National Hockey League hockey franchise. On 4 December, the NHL announced the approval of an expansion franchise in Seattle for the 2021-22 season, citing the city’s thriving market and the promise of a new “spectacularly re-designed” state-of-the-art facility. The total cost of the expansion, including the expansion fee for the hockey team and cost of the renovations, at $1.4 billion.

The arena’s roof, said to be shaped like a native Salish woven hat, was designed by Northwest modern architect Paul Thiry to top a three-acre facility for the Seattle World’s Fair of 1962. Originally it housed Washington state’s exhibits featuring a new-fangled machine called a UNIVAC computer and such exotic amenities as the Bubbleator—a plastic elevator that “took” visitors into an exhibit of the World of Tomorrow showcasing both hopeful and scary possible futures in the 21st century.

Showcasing Brazil to the world: Paulo Mendes da Rocha

Brazil's pavilion at Expo 1970

Star architect Paulo Mendes da Rocha, born in Espirito Santo on 25 October 1928, turns 90 today. Opening his Sao Paolo office in 1955, Mendes da Rocha quickly established himself as an architect of the Paulista school, which contrasted sophisticated engineering with a ‘rough’ finish.

It was this approach that saw Mendes da Rocha chosen to design Brazil’s pavilion at World Expo 1970 Osaka, a creation that served as a springboard for his career.

Westinghouse Time Capsule: 80 years on, still 4920 years to go...

Eighty years ago today, some seven months before the opening of Expo 1939 New York, a time capsule was buried in the middle of the Expo site. The instructions were clear: it was not to be dug up until the year 6939 – some 5,000 years later.

The bold time capsule project was an initiative of Westinghouse Electric & Manufacturing Company, with the aim of presenting a snapshot of the era while paying tribute to the Expo’s theme “The World of Tomorrow”. The electrical company aimed to immortalise life in the 1930s, based on the latest technologies and inventions of the era. By doing so, the highly publicised event was also familiarising people with the ‘modernity’ in which they lived.

Celebrating 10 Years of Expo 2008 Zaragoza

Bridge Pavilion

10 years ago today, Spain welcomed the world to Specialised Expo 2008 Zaragoza, the first of its kind. Over three months, the event gathered over five million visitors for an immersive journey into the theme “Water and Sustainable Development”, highlighting the issue of managing the Earth’s scarce resources and presenting solutions for the future.

The event was a watershed moment for the capital of Aragon, transforming the city’s riverbank and reinforcing its status as a global centre on water management. A decade later, a range of cultural events are being organised to commemorate the experience of Expo 2008, while also looking towards the ways in which the Expo’s physical and intangible legacy can be promoted.

Crossing the Ebro: Expo 2008 and the Third Millennium Bridge

Third Millennium Bridge

On 7 June 2008, the Third Millennium Bridge was inaugurated in Zaragoza, Spain, connecting the city centre to the site of Expo 2008, which opened to the public the following week. Spanning 279 metres across the Ebro River, the bridge is one of the largest infrastructure projects that accompanied the Expo, and remains, 10 years later, the largest of its kind in the world.

After 35 months of construction, the bridge’s prominent arch – reaching 25 metres above the deck - created a new addition to Zaragoza’s cityscape, while providing Expo visitors with a brightly lit focal point when returning home in the evening.
