An interesting fact: the overwhelming majority, if not all, of the construction is done without nails, only using wood-to-wood connections like dovetails. The whole structure is impervious to rusting of any load-bearing metal parts in the damp climate of a lake coast.
> According to the Russian carpentry traditions of that time, the Transfiguration Church was built of wood only with no nails apart from the domes and roof shingles. There are approximately 180,000 nails securing the 60,000 roof shingles.
More interesting how they fix these things with a technique borrowed from Norway: They hang up the whole structure from its top so it becomes loosely coupled, then remove and replace any bad wood then let it land on its own gravity again.
