Shater

Shater 

a tent-shaped superstructure in Russian architecture. Shatry were erected on bell towers and other towers, churches, and porches. They have the form of a tall pyramid on a base of four or more sides. In wooden architecture they were common through the late 18th century, and in stone architecture, in the 16th and 17th centuries.

Wooden shatry were formed by overlapping rows of logs with sides of decreasing length, and brick shatry, by sloping rows or by overlapping horizontal rows of brick.
