Guidant John Rose Minnesota Oval
From Wikipedia, the free encyclopedia
The Guidant John Rose Minnesota Oval is an outdoor ice rink in Roseville, Minnesota. Consisting of a 110,000 square foot (10,200 m²) concrete surface with 84 miles (135 km) of embedded cooling tubes, it is the largest artificial outdoor skating surface in the world. When the temperature is above 50 °F (10 °C)—the highest temperature at which an icy surface can be maintained—the concrete surface can be used for inline skating. The facility was constructed from June to December 1993. The earlier name was John Rose Minnesota Oval. Leaks in the cooling system were discovered in 2004, making the season's service uncertain.
John Rose Minnesota Oval hosted the Bandy World Championships for men in 1995 and for women in 2006.
In June 2005, the Guidant Foundation contributed $500,000 to allow for needed repairs to the facility's refrigeration system. The Oval's official name was changed in recognition of the Foundation's gift and continuing support.
There are many events and sports held at the Oval. The sports include bandy, ice hockey, and speed skating. In the summer months a skate park is put up for biking and skating.
