While some might suggest that posting photos of my trip to Ireland here is a bit off topic. I’d argue that it was research. Research for drawing better castles and the like on my fantasy maps as well as inspiration for my D&D games!
“Bunratty Castle is a large 15th-century tower house in County Clare, Ireland.” – Wikipedia
Personally I still thinks it’s a friggin’ castle, not a “tower house”.
Bunratty was intereting in that they actually staged the rooms with furniture and nick-nacks, so you could see what it might have look like with people living in there.
