The Castle Group of islands, Darrell's Island, Nonsuch Island and Paget Island are typical of those closed to most visitors.In November, 2012 two of the six Fairylands area islands were advertised for sale, for 0,000.They 0.504 acre Goose Island and 1.062 acre Bird Island.Both islands are within close proximity to the Point Shares and Fairylands neighborhoods.Agar's Hill there, which dominates the north side of the exclusive residential area of Point Shares, is so-named in honor of British shareholder in the 17th century Bermuda or Somers Isles Company, Sir Anthony Agar (1586-1637), also referred to in British history as Sir Anthony Aucher (Agar, Archer), Member of Parliament of Bishopsbourne, Kent, England.
Bermuda is said to have begun some 100 million year ago as a volcanic mountain, with the volcanoes having disappeared 70 million or so years ago.
(In most other countries, counties have entering and exiting signs). Our separate files on each Parish describe their islands.
Some have interesting histories, or are privately owned or both. Some are wild life reserves, with signs telling people on foot or in boats that landing is prohibited.
Oceanographers say the Bermuda Rise either juts up from the deep Atlantic Ocean floor in the form of three steep-sided mountains, the largest of which supports the Bermuda today, on the southern margin of a shallow water platform, with Challenger and Argus (or Plantagenet) Banks to the southwest, The Bermuda Mountain is longer - 32 miles - than the land area width and much wider - 16 miles wide - than the maximum land width of 1.5 miles.
At sea, the Argus and Challenger Banks are round and about 6 miles across.
