I have to say Russians of northern Russia are masters at woodwork.
Kizhi Pogost is part of World Heritage recognised by UNESCO.
The pogost of Kizhi (i.e. the Kizhi enclosure) is located on one of the many islands in Lake Onega, Russia. Two 18th-century wooden churches, and an octagonal clock tower, also in wood and built in 1862, can be seen there. These unusual constructions, in which carpenters created a bold visionary architecture, perpetuate an ancient model of parish space and are in harmony with the surrounding landscape.
Kizhi pogost is built without metal nails.
