Ice Castles is leaving downtown Stillwater and moving west. Its new home will be The Commons and Port of Excelsior on Lake Minnetonka. The Excelsior City Council approved the plans earlier this week, and construction will start soon, Ice Castles officials said Friday. The castle, which will be an acre in size, is expected to open at the end of December. Construction on the Stillwater Lift Bridge prevented Ice Castles from building again at Lowell Park, and another proposed location — Bridgeview Park south of downtown Stillwater — “did not provide the space or the resources needed to build an ice castle to the scale and standards our guests deserve and have come to expect,” CEO Ryan Davis said in a news release issued Friday. The popular winter attraction has been located in Lowell Park for the past two years. About 100,000 people toured the attraction last year. Crowds ranged from 5,000 people on its busiest day to 200 people on its slowest; the average daily count was 1,500. The economic impact of Ice Castles in Stillwater last year was $2.5 million, city officials have said. Ice Castles also builds its attraction annually in Midway, Utah; Dillon, Colo.; Lincoln, N.H.; Lake Geneva, Wis.; and Edmonton, Canada.
