The Black watch well. It is a bit unkempt, but a good piece of history. I believe it is just a few miles from down town Hamilton.
it was dug by the Reg. in 1849 to help the poor and their cattle.

Bermuda's Black Watch Pass and Black Watch Well at the junction with the North Shore Road are named in tribute. Black Watch Pass was dug in 1847. Black Watch soldiers cut through a massive limestone hill between Pembroke March and North Shore Road, to provide Hamilton-bound or exiting local traffic with a level access to and from the town, now city, of Hamilton. Popular with the island's visitors, the sheer drama of the towering walls gives the pass an appearance of a deep, razor-thin gauge piercing through sold limestone rock to the sea beyond. The structure was built entirely by hand. Black Watch Well was dug in 1849. When the Governor of the period ordered British soldiers to seek a fresh water supply for the poor of Pembroke Parish and their cattle during a prolonged drought, the Black Watch was the first to volunteer and dug so thoroughly the facility still exists today. At the site, a sign says: "This is the well of the Black Watch - so-called in memory of some soldiers from the First Battalion, 42nd Regiment, Royal Highlanders, by whom it was sunk for the relief of the poor and their cattle. " One of the officers was Captain G. W. MacQuarie, who lived in St. George's at what was then Rendell House, later the Redan Hotel, now Clyde's Cafe. It is believed one of the soldiers was Richard Brackey, married, whose son was born in Bermuda. Several of this unit's soldiers died in Bermuda from yellow fever and are buried at St. Peter's Church in St. George's. They include Ensign Maitland, Ensign Abercromby and beside them the grave of bandmaster Philip Goldbergh. Many members died and were buried elsewhere in Bermuda from yellow fever.
