Bell Bock
Bell Bock, or Inch Cape, a dangerous reef in the German Ocean near the mouth of the Tay. On it is built a lighthouse erected in 1807-10 by Robert Stevenson from plans by Rennie. The height of this lighthouse is 120 feet, its cost was £60,000, and besides a revolving light it has two bells to be rung in foggy weather. The rock has the reputation of having been a source of danger from early times.
