ELI5: Explain Like I'm 5

Rock of Cashel

The Rock of Cashel is a big pile of rocks in Ireland that people built a long time ago. It's a castle, a church, and a graveyard all mashed together. Lots of important people like kings and bishops used to live there and pray there. It's a very famous and special place that lots of people like to visit and take pictures of. It's kinda like a big playground for grown-ups where they can imagine what life was like a long, long time ago.
