The popular Ice Castles in Stillwater will be closed this week.

We're at the beginning of a nine-day stretch with temperatures above freezing in the Twin Cities, which means things will melt. Including the Ice Castles.

The Ice Castles' walls will deteriorate a little bit (structurally, they'll be fine), but the problem is with the floor that's made with 8 inches of crushed ice and snow. That'll melt for sure, and make a slushy, wet mess for anyone who tours the castles, the Greater Stillwater Chamber of Commerce said Wednesday.

That's not fun for anyone, so the Ice Castles will be closed on Thursday and Friday, and likely through the weekend into next week.

But once the temperatures get below freezing again (it's Minnesota, so we know they will), workers will be able to fix the floors and the Ice Castles will reopen.

If the Ice Castles are closed through the weekend, it'll be a major bummer for the 8,000 to 10,000 people who already have tickets, the Pioneer Press reports, noting many of the people who bought tickets for the weekend are visiting Stillwater for Hockey Day Minnesota on Saturday. (Note: Hockey Day Minnesota events will go on, rain or shine.)

If you already bought tickets and it'll be closed, you can contact info@icecastles.com to reschedule your visit.
