 Commonwealth Stadium in Edmonton received major upgrades to host the 2001 World Championships in Athletics, and continues to host the Edmonton Eskimos, but has only hosted the city's soccer team, FC Edmonton, for three matches in Canada's national cup competition, the Canadian Championship.An added benefit of single-sport stadiums that was impossible with the "concrete donut" design of the multipurpose stadiums is improved panoramic views of areas outside the stadium, such as mountains, bodies of water, or city skylines.Examples include CenturyLink Field and T-Mobile Park, which replaced the Kingdome in Seattle, and Heinz Field and PNC Park, which replaced Three Rivers Stadium in Pittsburgh.
