Where am I?

Using the following clues (the map above is purely decorative) in combination with Street View, work out my location.

Although Roman, THC’s chief puzzlewright, would be interested to know how long it takes you to solve this solo foxer, he’d rather you didn’t put spoilers or solutions in the comments.

Today I’m not in Wales, but if I told you the name of the town I’m in, you might think I was. Roughly 600 metres from a plant that turns sea water into drinking water, and a similar distance from a crude 18th Century ‘mortar’, I’m in a country that has competed at 21 Olympic Games and never won a medal. Said country gained its independence in the mid Sixties, has been visited by a Supreme Leader of North Korea, and has the same last two letters as its capital city.

You are probably in the right place if you can see…

• A BMW X3
• No road markings
• Floodlights
• A soldier
• A clocktower
• A ferry route used by hydrofoils
• Open ground unsuitable for agriculture
• A door- and windowless structure occupied by around a dozen people
• A ‘risk of explosion’ sign
• The words ‘Cycle lane’
