Intense navigation in the northernmost reaches of the Yenisei River during the Soviet era produced a rich industrial heritage. Among the more conspicuous objects are the remains of shore navigational aids, particularly leading lights and beacon towers. The surviving structures offer insights into the navigation methods used in this part of the Arctic. Navigational aides were also among the last industrial structures in the Soviet Arctic to be built of wood. Besides, they are important examples of structural engineering in the Arctic, meaning that they were designed to cope with the harsh environment.
