Kryal Castle is still on the market months after it was put up for sale.
The ownership consortium decided to sell earlier this year after refurbishing the attraction over a few years.
A spokesperson for Colliers International said they did not have any comment on how the sale was progressing.
The castle has taken a long time to sell in the past, but agent Guy Wells said he was already fielding interest when the sale was announced in late March.
“Given the growth in visitation and buyer appetite, they now feel the time is right for a new owner to usher this unique property into its next phase,” he said.
“Both local and offshore interest is already being fielded.”
The castle’s builder Keith Ryall died last year and was farewelled in true medieval style within its walls.
The castle got a boost this week with resident knight Phil Leitch winning a prestigious international jousting contest, the Tournoi de Sainte Suzanne.
He showed his superiority in the solid and balsa lance jousts, foot combat, skill at arms and the mounted melee.
Before the current owners took over the castle had gone through a tumultuous sale process, with a deal falling through and an offer from brothel owners rejected.
In late 2011 the sale went through for an undisclosed amount and since then the owners group has sunk millions into the castle.
The real estate pitch from Colliers International pushes further accommodation possibilities and its current visitor numbers as a reason to invest.
“Kryal Castle has traction in the marketplace and has set the foundation of a highly successful, unique tourism, leisure and events business, from which significant growth can become a reality delivering an excellent return on investment,” Mr Wells said.
“The low level of investment necessary to increase the accommodation capacity and include caravan park or camping possibilities would allow for increased revenue and would open the castle up to an even wider customer base.”
“The ability to further add value through additional accommodation and events capabilities mean that the next five to 10 years will see this property grow exponentially with the potential to extensively add to this exciting attraction.”
