Tiles of Bertre

Summary

A bright phenomenon left marks on a roof in 1989. An insomniac man saw a strong light above his house and, upon approaching, observed a luminous object shaped like a spinning top over a field. The phenomenon disappeared silently and odorlessly. The next day, he noticed the tiles were discolored and displaced, forming a gutter. The contractor confirmed the tiles were twisted clockwise over several meters and the ridge was damaged.

The investigation found no conventional explanation. The affected tiles suggested thermal or magnetic influence, but no signs of combustion or natural causes were found. The case remains unsolved, with a clear witness account and physical evidence that does not fit known phenomena.
