It is pleasantly situated on the river Inny, not far from the fine granite peak and seamark named Brown Willey, which rises to the height of 1,360 feet, and on which most of the streams in the district take their rise. The living is a vicarage* in the diocese of Exeter, value £320, in the patronage of the Dean and Chapter of Exeter. The church is dedicated to St. Nunn, or Noneth, whose burial-place it was, and who was the mother of St. David of Wales. The tower of this church is loftier than any other in Cornwall, except that of Probus. The Wesleyan Methodists and Bible Christians have chapels here. There is also a district church at the village of Bolventer, and a chapel for Bible Christians. Tregune Consols is a copper and tin mine. In this parish is Trelawney, the ancient seat of the family of that name. A little to the north of Altarnun is a pool, or lake, called Dosmery Pool, the only lake in the county, and concerning which some "strange conceits "were held of old. It is in the midst of the moors, and is about a mile in circumference, having no visible spring, nor any outlet. Cattle fairs are held at Five Lanes, one of the hamlets in this parish, on the second Monday after the 7th of July, and the last Thursday in October.
