EXCELSIOR, Minn. (WCCO) — The annual showcase of ice castles will open Saturday in Excelsior.

The castles, formerly displayed in Stillwater, have been in the works for about five weeks. Artists must grow, harvest and hand-place the ice to create the tunnels, fountains, slides, thrones and ice towers, which are also embedded with color-changing LED lights.
