Eshaness, Shetland. Built by David in 1929. Now owned by Shetland Amenity Trust and available for tourist rentals! How cool is that? The roof is reinforced concrete and can withstand frequent batterings not just by wind but by the stones and indeed large boulders thrown up over the 61-metre cliffs. Seriously. Extreme holidaymaking! In glorious weather today, though. Northern Lighthouse Board info here: http://www.nlb.org.uk/LighthouseLibrary/Lighthouse/Eshaness/
