Re: Contest/Game - Identify this picture
Labatt is very close, perhaps a nm or two from the marina in foreground, but perhaps that's close enough. Weymouth has its own in-city port, but the manmade port (which actually borders on "downtown" Weymouth) in the photo is known as Portland Harbor. The land mass in the background is the Isle of Portland. This area was the sailing venue for the 2012 summer Olympics.
The "rocky" clue refers to the limestone quarries there which produce Portland stone, used in Britain and elsewhere in prominent buidlings, like St. Pauls and the UN. This area is within the Jurassic Coast of Britain and is a tourist destination for fossil hunters. There are lots of fossilized mollusks--the most memorable being the large ammonites.
There is also a castle/fort dating back at least to Henry VIII, but it hasn't been manned for about 200 years. The more recent military history relates to Royal Navy R&D, but that presence has diminished over the past few decades.
Since the Isle of Portland is within the "Borough of Weymouth and Portland", Labatt scores on a technicality! Your turn to post Labatt.
