This image is from harbor at the isle of Lindisfarne, also known as Holy Island, and the castle in the background is Lindisfarne Castle.
The two upturned boats in the foreground have been cut in half and made into sheds - I guess to store tools, nets, ropes; tools of the trade for the fisherman who owns it. Life as a fisherman is hard with a lot of toil, sweat and blood, and even tears for those lost at sea - sons, brothers, husbands and fathers.
To me the two upturned boats represent a much more interesting bit of history than the castle in the background. Their history started just a few generations ago - it could have been my grandfathers boat, my fathers shed.
