Set at the mouth of the Shannon, Limerick city is the third-largest on the island. One moment, you’re wandering through the Middle Ages at King John’s Castle. The next, you’re in a rejuvenated Milk Market. One minute you’re amongst old Georgian townhouses, then you’re sipping cocktails in a five-star hotel. There’s no way to categorise Limerick city, and the locals wouldn’t have it any other way.
