Postcard from the United Kingdom!

Today I got a great postcard from the United Kingdom! The postcard features multiple views of some of the castles built by King Edward I in North Wales. On the card we see Caernarfon, Conwy, Beaumaris, and Harlech castles. These were built during his reign in the 13th century. These castles were noteworthy for their mix of palatial living quarters and intelligent military defenses. Thanks Ollie!
