The district is chiefly agricultural. Near the village of Ballasalla are the ruins of Rushen Abbey, founded in 1098, and dissolved late in the reign of Elizabeth I of England, and an ancient packhorse bridge over the Silver Burn, called the Crossag, or Monk's Bridge, too narrow for vehicles. Derbyhaven is a tiny hamlet on an isthmus, with a natural harbour, protected by a small breakwater. St Mark's, in the north of the parish, is a small agricultural village clustered round a chapel of ease.
