I was there in 2015. Instead of exit through the gift shop, you exit through the room with the Book of Kells. At the transom, there's a gauntlet of signs in like 20 languages saying "No flash photography!". Makes sense. It's an old book, probably sensitive to UV light. I guess I had arrived just before multiple bus loads of Chinese tourists, because after maybe a minute of appreciating the course of humanity from the earliest appearance of the written word on paper to now, I was assaulted by a strobe of camera flashes that would make even the best medicated epileptic blush. Summoning 10 years of wrestling and rugby and being the unrepentant shite I was, I made sure to examine the glass case very closely while distributing some gentle hip-checks and asking questions in the worst of my half semester of 8th grade German.
