Otterburn Castle Country House Hotel is on the market with Christie & Co with a guide price £1,750,000.
Owner, Elena Wynn, who has operated and lived in the castle for the past five years, said “I have had some wonderful times here and feel proud to be the custodian of such a magnificent building.
"However, I am not a hotelier and I feel that the time is right to allow the full potential of the castle and the business to be realised in the hands of a new owner.”
Mark Worley, director in Christie & Co’s hospitality team, said: “We’re thrilled to bring the beautiful Otterburn Castle Country House Hotel to market and expect to receive high levels of interest for this property.
"The leisure and hospitality industry is bracing itself for what should hopefully be a fantastic summer, as the pent-up demand for staycations and leisure breaks is released once lockdown restrictions are eased.
"This projected massive upsurge in trade and profits has proved to be a huge incentive and motivation for buyers to purchase tourist-related businesses over recent months.
“The sale of Otterburn Castle not only provides the opportunity for a buyer to capitalise on the spring, summer and autumn periods, but also to tap into the wedding trade, a sector which also has a very rosy future.”
Otterburn Castle was initially gifted to Robert D’Umphraville, a cousin of William the Conqueror, during the 11th Century, in recognition of his services.
The estate has a rich history itself dating back to the 14th Century, when a pele tower was constructed at the site to repel the Scots and this formed an integral part of the Battle of Otterburn in 1388.
The Grade II listed castle hotel currently standing today was rebuilt in the 19th century with stone from the original tower.
The 17-bedroom hotel is set in four acres of gardens and sloping woodland, with a further 28 acres of land available by separate negotiation.
The castle also features a grand reception with an original oak staircase, breakfast room, lounge, bar and restaurant with a private dining area and an array of meeting and event spaces including the Garden Room and a permanent outdoor marquee.
