The best castle I have ever seen, by far!

Good morning! These are some pics from my trip to Ireland a few months ago...The above is a Castle, and the one below this is The Giant`s Causeway, and the one below that is some ruins and graves from Aran`s Island. In Japan, the are many castles, like Osaka Castle, Himeji Castle, Okayama Castle, Niji Castle...I have been to a bunch in Japan. Osaka Castle, a famous site, is good to look at from the outside, and the park and moat surrounding it is cool, and the view from the top is spectacular, but the inside is not so special I think. It`s too modern, too much about history... Himeji Castle is nice, and feels like a castle. BUT the Castles in Oreland really take the cake!!! There is no comparison!
In a few days Thanksgiving, an American National Holiday, is coming. Do you know what the meaning of Thanksgiving is? Do you know what American people typically do on Thanksgiving?
