Gheel [1]

A town in Belgium, situated on a fertile spot in the midst of the sandy plain called the Campine, 26 m. SE. of Antwerp; it has been for centuries celebrated as an asylum for the insane, who (about 1300) are now boarded out among the peasants; these cottage asylums are under government control, and the board of the patients in most cases is guaranteed.
