In China each year, the Harbin Ice and Snow Festival features both buildings and sculptures constructed entirely of ice and snow, which are augmented with nighttime illumination. Here are a few highlights from this year's festival:

China doesn't have a lockdown on spectacular ice and snow architecture. The Pyotr Yeropkin-designed 20 meter tall by 50 meter wide Russian Ice Palace, which has been reconstructed every year since 2005 (although the design dates back to 1740) in St. Petersburg, has interior spaces with custom ice furniture:

Quebec's Hotel de Glace offers a functional, if chilly, opportunity to experience ice and snow architecture. Each year, guests can stay inside one of its 44 rooms (some of which come with seemingly oxymoronic amenities, like a fireplace):

Lastly, there is the SnowCastle of Kemi by the Gulf of Bothnia in Finland, which is constructed annually and features an accompanying SnowRestaurant, SnowChapel, and SnowHotel. The SnowCastle's official website is careful to note that "the temperature in the [Snow]Restaurant is always about -5 degrees Celsius and we do recommend you to dress warmly."
