Stadiums can ruin a city–but they can also save it

Throughout history, stadiums have been transformed into villages, shopping centers, and more. The next wave of stadiums could power cities.

Stadiums Economic Benefits

Stadiums are among the oldest forms of urban architecture: From Olympia to Rome, stadiums were at the center of Western cities, well before the great medieval cathedrals and the railroad stations of the industrial revolution.

Today, however, stadiums are regarded with growing skepticism. Construction costs can soar above $1 billion, and stadiums finished for major events such as the Olympic Games or the FIFA World Cup have notably fallen into disuse and disrepair.

But this need not be the case. History shows that stadiums can drive urban development and adapt to the culture of every age. Architects and planners are finding new ways to adapt the monofunctional sports arenas that became emblematic of modernization during the 20th century.

Arles Amphitheater in France

The amphitheater of Arles in France, with a capacity of 25,000 spectators, is perhaps the best example of just how versatile stadiums can be. Built by the Romans in 90 A.D., Arles amphitheater became a fortress with four towers after the fifth century, and was then transformed into a village containing more than 200 houses. With the growing interest in conservation during the 19th century, the structure was converted back into an arena for bull racing.

The imposing arena of Verona, Italy, with space for 30,000 spectators, was built 60 years before the Arles amphitheater and 40 years before the Colosseum. It has endured the centuries and today is considered one of the sacred temples of opera, thanks to its outstanding acoustics.

Research by Taisuke Kuroda of Kanto Gaukin University has revealedthe Piazza dell’Anfiteatro in Lucca (capacity: 10,000) as another impressive example of an amphitheater becoming absorbed into the fabric of a city.

The Piazza evolved in a similar way to Arles, and was progressively filled with buildings from the medieval period until the 19th century, variously used as houses, a salt deposit, a powder magazine, and a prison. But rather than reverting to an arena, it became a market square, designed by Romanticist architect Lorenzo Nottolini. Today, the ruins of the amphitheater remain embedded in the shops and residences surrounding the public square.

There are lots of similarities between modern stadiums and the ancient amphitheaters intended for games. But some of the flexibility of such arenas was lost at the beginning of the 20th century, as stadiums were developed using new materials such as steel and reinforced concrete, and made use of bright lights for nighttime matches.

Many modern stadiums are located in suburban areas, designed for sporting use only and surrounded by large concrete parking lots. These factors mean that they can be less accessible to the general public, require more energy to run, and contribute to urban heat.

But architects such as Herzog & De Meuron, Zaha Hadid Architects, and Toyo Ito see scope for the stadium to help improve the city. Among the current strategies, two seem to be having particular success: the stadium as an urban hub, and as a power plant.

There’s a trend for stadiums to be equipped with public spaces and services that serve a function beyond sports, such as hotels, retail outlets, conference centers, restaurants and bars, children’s playgrounds, and green space. Creating mixed-use developments such as this reinforces compactness and multi-functionality, making more efficient use of land and helping to regenerate urban spaces.

This opens the space up to families and a wider cross section of the middle class, instead of catering only to sportspeople and supporters. There have been many examples of this in the U.K.: the mixed-use facilities at Wembley and the Old Trafford have become a blueprint for many other stadiums in the world. And the Fulham FC Riverside Stand Redevelopment, due to be completed in the next two years, will extend the riverside boardwalk, adding housing and retail.

The phenomenon of stadiums as power stations has arisen from the idea that energy problems can be overcome by integrating interconnected buildings by means of a smart grid, which is an electricity supply network that uses digital communications technology to detect and react to local changes in usage, without significant energy losses. Stadiums are ideal for these purposes, because their canopies have a large surface area for the installation of photovoltaic panels, and rise high enough (more than 130 feet) to make use of micro wind turbines.

Freiburg Mage Solar Stadium is the first of a new generation of stadiums as power generators, which also includes the Amsterdam Arena and the Taiwanese Kaohsiung National Stadium.

Taiwan’s Kaohsiung National Stadium, inaugurated in 2009, has 8,844 photovoltaic panels producing up 1.14GWh of electricity annually. This reduces the annual output of carbon dioxide by 660 tons and supplies up to 80% of the surrounding area when not in use. This is proof that a stadium can serve its city, and have a decidedly positive impact in terms of reducing of CO₂ emissions.

Stadiums remain the immortal engine of the city. In every era, the stadium has acquired new value and uses: from military garrison to residential village, public space to theater, and most recently, a field for experimentation in advanced engineering. Now, rather than becoming something else, the stadium brings together multiple functions to help cities create a sustainable future.
