The church was built in the 13th century - far away from the coastline. But since then wind and water have been taking their toll with two to three meters of land falling down onto the beach every year.
Yes, falling down. It's not enough that the sea is getting closer. A meters high drop awaits the grass, dirt and an occosional skeleton from the church's old graveyard.
The upper half of the church has been taken off now for reasons concerning safety and preservations. And with about 10 meters of land remaining, it won't be long before the sea has taken so much of the land that the whole church needs to be taken down.
