About 70 children are educated in three private schools. At Rathugh are two large raths, or moats, from which this place derives its name, and there is a third at a short distance. One of these, which is very remarkable, is supposed to have been the mausoleum of a native prince. At Ballybroider are vestiges of an old fortified house, and of another at Little Ross.
