This version, however, was reduced to ashes by a raging fire and a new castle was constructed on the site again by the Marquis of Donegal in the nineteenth century. That’s the iteration that we see today.

The gorgeous fairytale-esque facade of this castle made it quite a popular wedding and reception location from the 40s to the 70s.

Sir Basil Brooke later rebuilt it in a Jacobean style. Today, a 17th-century boundary wall surrounds the castle.

It was the O’Carroll family who gave the facade a Gothic revamp. The castle was once home to the great inventor William Parsons, the Third Earl of Rosse.

Today, Birr stands as proud and beautiful as ever, while housing Gardens and Science Center. It is still owned and occupied by the Parsons family, so only a portion of the castle is open to the public. The surrounding meadows are a sight to behold, but botanists and nature aficionados are blown away by the 500-year-old oak tree that resides in the castle grounds.
