King John's Castle
You will first notice the massive stone walls of King John's Castle, also known as Limerick Castle. This military museum is located on King's Island next to the River Shannon. While the castle's inception was 1210 and it was built on the orders of King John of England in 1200, the ground beneath it holds older secrets. Archaeological excavations in 1900 uncovered remains of a Viking settlement at the site. This confirms that Vikings lived on the island as far back as 922. Today, the site is recognized as a national monument of Ireland. I've found the river breeze makes for a great spot to pause and look at the fortifications.
