1. Dublin Castle
One of the most significant symbols of power in Ireland is Dublin Castle. This 13th-century castle, which is more of a multi-building complex, was built on a Viking settlement. The castle served as the government complex for the English then British rule for centuries and now serves as a main tourist destination.
Some of the castle highlights include extensive decorative arts in the form of formal portraits of rulers and royalty, as well as period furniture. Be sure to visit The Chapel Royal, a Gothic Revival chapel, which has been at Dublin Castle since 1242, and the castle gardens that have been here since the early 17th century, featuring the Dubh Linn Garden, where patterns of sea serpents are cut into the lawn.
Beneath the castle, you can see ongoing excavations of Viking defenses that have been preserved. You can even go down steps to see the original moat.
2. Trim Castle
For a castle worthy of bragging rights after your vacation, the Trim Castle is a must-visit. This is where Mel Gibson filmed the movie Braveheart, so you will likely recognize the iconic features of this powerful Norman Irish fortress. Construction started on the Trim Castle in 1176 and took 30 years to complete.
This massive structure has a 20-sided tower, masterful curtain wall, and moat. It is the largest Anglo-Norman castle in Ireland and has also served as a prison and private home over the centuries.
Now, it is a popular tourist attraction and well worth your time to visit. You can only take a guided tour of the castle, but you can explore the riverside grounds on your own. You can also plan a stay at the Trim Castle Hotel and live like royalty during your trip.
