But chances are, you've never heard about it nor visited.
McDermott's Castle sits on 0.57 of an acre in the middle of the lake and dates back to the 12th Century.
It was fully operational and lived in for four centuries.
The castle was rebuilt as a summer house in the 18th century but burnt to the ground during a fire in the second World War.
Although nobody lives in the castle at the moment, you have to imagine that it's absolutely primed for a redevelopment and would be the most romantic getaway you could ever imagine....
The castle has a rich history...
The McDermott’s official residence was on The Rock, now called Castle Island. As space was limited on this small island, they had another residence on the mainland where the Moylurg Tower stands today.
The McDermotts ruled this area until the 17th century, when it was granted to the King family from England under the Cromwellian settlement.
The King family spent their time between the town of Boyle and Moylurg, which they renamed Rockingham. One of the large mansions they built was called Rockingham House and was built where the Moylurg Tower now stands.
Judging by the few people who have discovered the castle, it could be the ultimate set for a movie or just a dream hotel...
Someone make it happen!
