It warms my heart to see so many lighthouses beaming out into the chilly night in the far north of the British Isles, near Orkney and the Shetlands.  

But what are those two lighthouses due west of Orkney?  I know of no land there.  They're well north of the Hebrides.

It's also fun to see there's a lighthouse in the middle of Scotland!  I think that one is on Loch Ness.  But where, exactly?

Odd that there are none on the west coast of Ireland.

So you can see the details, I'm only showing you the top of this beautiful map made by @49f821b2,  The whole thing is here:

"West coast of Ireland" isn't exactly part of the United Kingdom though, is it? They're likely just not shown on that particular map.

 @b4c50e1b @49f821b2 The title of the linked map is lighthouses go the United Kingdom. The west coat of Ireland isn't in the United Kingdom. But you've made me curious about the two ones west of Orkney.
