The surviving windmill tower on Green Castle is different in construction details from all others found on the island.  In 1974 test results from the Institute of Geophysics at the University of California, U.S.A., showed that the wood dated from the 14th or early 15th century.  There has been speculation on the purpose of the windmill in those days and one is that it still stands on Green Castle because it was intended to be not only a mill but a stronghold to retire to in case of trouble.  The walls are six feet thick.

As you sit on the breezy verandah of the Estate House or around the pool you can observe the many hummingbirds who come to feed either from the nectar on the many flowers in the garden or the bird feeders hanging from the verandah ceiling.  The Red-billed Streamer tail is the most common in Jamaica and the most spectacular hummingbird of the West Indies.  The male has a red, black-tipped bill and the long streamers, which due to their shape produce a hum in flight.  When perched the streamers are usually crossed.  These birds feed on nectar and small insects.  Endemic to Jamaica, it’s a beauty to just sit and relax and observe the birds as they move around the garden on the Estate house – another reason to visit Green Castle.

Jack’s Bay Beach, Green Castle’s own private beach was used in colonial times as a pier to ship commodity crops to England and the United States as well as a landing dock for slaves.  The beach is 100% natural and has not been physically altered like many of the beaches in Jamaica.  The sand at Jack’s Bay Beach is composed of small dark pebbles and the water is clean and clear, but not the turquoise most people think of when they think of the Caribbean.  However, Jack’s Bay harbors amazing flora and fauna in its nearby reef and people who go to the beach get to experience a natural beach with lots of history.  There is a bar that serves a variety of non-alcoholic and alcoholic beverages, freshly prepared food and restroom facilities.  A small fee is charged in exchange for use of the beach and it’s amenities.  The beach can also be rented for functions day or night.   It’s a great place for locals and travelers  alike.
