It will probably come as no surprise that, while in Dublin, I made a point to visit the natural history museum there. It is a gem of a place, still set up like a true Victorian museum. I highly recommend you visit it if you're ever in Ireland.
I was not able to schedule a full-blown photo shoot (we simply weren't there long enough), but I had a wonderful time there, and was able to take a few snapshots, at least!
Can you recommend a natural history museum in your town?
