The Old Well Inn, which takes its name from a former well inside its cellar and dates back to Tudor times, has just come onto the market in Durham.
The former coaching inn is in the sought-after market town of Barnard Castle.
Martin Stansmore, of Fleurets' Leeds office, said the pub is on an old Roman-built waterway in the heart of upper Tees-side, dubbed, "England's last wilderness".
"The ruins of the castle create a stunning backdrop for the Old Well which, coupled with its location close to the Bowes Museum, ensures a good flow of trade all year round," he added.
Inside, there is a traditional front bar with an open fireplace.
The main bar is at the rear of the property and serves as a popular place to enjoy pre-dinner drinks. It leads into the main dining room and conservatory, which has 40 covers. The conservatory, which looks out over the beer garden, can be sectioned off from the main dining area if required.
The residents' lounge, which is accessed through the conservatory, features a Scandinavian wood-burning stove.
At the front of the inn there is a fully-licensed restaurant, mainly used at present as the breakfast room for residents of the hotel.
There are 10 en-suite letting bedrooms a family room, three twin and six double rooms many of which feature open fires, exposed brickwork and timber beams.
The property has a secluded beer garden that runs up to the castle wall.
Fleurets is seeking £50,000 for the leasehold and contents.
