Agia Theodora is a small Byzantine church and has 17 holly and maple trees growing from its roof.

Most of them are taller than 30m and it’s phenomenal as there is only one root about the thickness of an arm that is visible beside the entrance.Even more amazing is its tiny barrel vaulted interior where, except for one wispy bit of green there is not one sign of the trees or roots.
Another fascinating fact about the location is that a river runs beneath this church and irrigates the trees.
Agia Theodora’s church has become a popular pilgrimage site for Greeks and her feast day is today, September 11, where thousands and thousands of people from all across Greece will travel here to pray. Source:
