Caernarfon Castle
Snowdonia National Park, Wales, United Kingdom (UK)
Experience
This imposing medieval fortress was originally built in the 11th century, then enhanced by King Edward I at the end of the 13th century. The scene of many a siege and sacking, and then increasingly unnecessary, it fell into disrepair so that only the shell walls remain today.
