This building of ice blocks appears in Baikalsk for the third time. Baikalsk is a small town not far from Irkutsk on the southern bank of the Baikal Lake. Winters are long and severeÂ here. This allows to build anything from ice and it will stand for a long time. But it’s hard to imagine two incompatible things together – ice walls and 120 Celsius degrees heat inside a sauna. But it’s true. Water-boiling temperatures are divided from freezing ice only with a 1-inch-thick partition.
