On a small FPV tour to Belgium we stopped at an abandoned church with a retirement home. The old people's home appears to have burned massively, but the church was apparently spared.
It looks like they initially tried to renovate the buildings, but for some unknown reason they simply stopped. The complex has probably been empty for years now and nature is slowly taking over again.
It's a shame that the church is in very poor condition and vandalism has already taken place. The destruction of this particular place feels even worse than what you usually see in abandoned places and buildings.
