A small castle at the E end of that hill occupies the site of a very ancient fortalice, supposed to have been built by the Britons; is itself an ancient structure; has been enlarged and altered, and is thought to have originated the name Illogan, the last two syllables of which signify, in Cornish, "the white tower" or "the tower on the downs." Remains of a circular fortification, called the Old Castle, are a little to the W, and a column to the memory of the late Lord Dunstanville is on the hill's summit. Druidical remains are numerous. Mines of tin are extensively worked, building stone is quarried, and the West Cornwall railway, with a branch to Portreath, facilitates the traffic. The Redruth Workhouse is here.
