"Where the mountains rise to the oft-changing skies, And the castle stands stately and gray; Where the still lake still lies, beneath that wild, rugged hill, In the vale of lovely Glenveagh..." By: Herbert W.K. Sterritt

We really enjoyed visiting Ross Castle in Killarney. This castle is particularly impressive from the outside and the surroundings with the beautiful lake are just totally romantic. I personally didn't find the interior that spectacular, but once you've had a look around the castle you'll be rewarded with a fantastic view at the top!

Dublin Castle was built in the early 13th century on the site of a Viking settlement and served for centuries as the seat of the English and later British administration of Ireland. In 1922, after Ireland's independence, Dublin Castle was handed over to the new Irish government. Today it is a major government complex and a major tourist attraction (Source: https://www.dublincastle.ie/)

- The ruins of 16th century Minard Castle are located right on the beach and offer magnificent views over Dingle Bay towards the Iveragh Peninsula.

One of Ireland's most famous and picturesque sights: a mountain with a fortified monastery ruin and another monastery ruin in the valley. A beautiful complex; solitude, however, is something else entirely.
