Hello @sharker, welcome to the Architecture + Design Community! It's fascinating to see a wooden chapel built in the 18th century still look intact in this day and age.

Thank! I was delighted to find your community here on the Hive, hope to learn interesting things here, and also post here periodically.
As for the chapel, yes, I myself find it difficult to imagine that something wooden can stand and be used by people for centuries. It's rare, but it's possible - and that's great :)
