The box has been in the Parsons' family for over 150 years.
The owner's of Birr Castle are selling their private box in London's Albert Hall for €3.5 million.
The Times of London is reporting the box is being sold by Brendan and Alison Parsons, and it's been in the family since the venue was opened in 1871.
Mr. Parsons' great-great-grandfather paid £100 for Box 14, with a 999 year lease.
The box also comes with an annual bill of €16,000, which will go towards the maintenance of the iconic venue in London.
The Earl and Countess say they're selling the box because they don't use it as often as they'd like.
