A Northern Irish castle that featured on the hit HBO show "Game of Thrones" is on the market for £625,000 ($810,000). 

Situated in Markethill, County Armagh, Gosford Castle shot to fame when it appeared as Riverrun, home of House Tully, on the hugely popular fantasy series.

The castle was previously listed in 2019 and has since been divided into a number of separate properties. 

The Bastian Gate division of the original property is currently on the market for £625,000 and is listed by CPS Property. 

The property is located within the walls of Gosford Castle itself and within the grounds of the 600-acre Gosford Forest Park, which features a herd of red deer, five children's play parks, a walled garden, two mill ponds, and several walking and cycling tracks. 

The three-story Bastian Gate features two kitchens, three bedrooms, a foyer, a reception room, a lounge area, and an entertainment area, while the interior of the property has been renovated to boast a variety of modern comforts.

It also features a modern lift to all three floors, making the property accessible to all kinds of buyers. 

Art O'Hagan, managing director of CPS Property, described the castle as "something very unique". 

"It’s very rare. We have been in business for 38 years, and I can say this is definitely a rare find," O'Hagan told the Belfast Telegraph. 

"We in CPS Property are delighted to be the selected listing agent to bring such a beautiful unique property to the open market." 

O'Hagan said the property was built between 1819 and 1825 for Archibald Acheson, the 2nd Earl of Gosford. 

The castle was designed by architect Thomas Hopper, who was known for his Gothic revival style characterized by battlements, turrets, and large windows. 

The castle was also used to house soldiers during the Second World War.
