I just looked that up. An impressive feat indeed, especially at the
time. But it was done with a different sort of construction, using
girders, notably to hold up the ceiling. The various Ice Hotels around
the world these days are generally made entirely of snow and ice. All of
the rooms have arched ceilings, some have columns of ice as well. I saw
a video of how the one in Quebec is built a few years ago. It involves
wooden forms which are removed once the snow has hardened enough to
support its weight.
