Last weekend the boys and I hiked up to see the Katsuren Castle Ruins. It was so beautiful overlooking the Pacific Ocean. It was built in the 13th century and came under attack in 1458 by the Ryukyuan Army. Just last year, ancient Roman coins believed to date back to the third or fourth century were discovered in the ruins. The boys loved exploring the Castle and learning about the history. We went right before sunset and it was absolutely beautiful!
