Ghost in the Furrengasse
Furrengasse, Lucerne, Switzerland
In 1607 a strange ghost was sighted in the Furrengasse in Lucerne. In
the light of the lanterns it appeared as a human figure and resembled a
lean, tall man. Then it changed its appearance and grew in height until
it surpassed the size of a five-metre high lansquenet spear.
