Turelbaach is a Castle in Grosbous, Luxembourg. Once upon a time in 1964, Pol Gilson decided to build a second home in the middle of a green area near Bigelbach in the north-east of the Grand Duchy. His first construction, made out of wood, was destroyed in a fire in 1973. Gilson remained imperturbable even after that setback, and started with a new construction, this time using stone and concrete.
Gilson was the the son of a stonemason, who provided him with enough knowledge to start the endeavour. He further consulted professionals in the domains unknown to him, and only on one occasion loaned heavy machinery to help dig the moat around the castle walls. The rest was all completed by Gilson himself in autodidactic manner.
