The Hall exudes the impression of age from the moment you pass through the Renaissance gate posts. The floors are uneven, the doorways low and the stairway spirals precipitously upwards, its stone steps worn from centuries of use. There is a priests' hole which leads down from Room 11 to the fireplace in the bar. In 17th Century England it was difficult - if not illegal - to be Catholic. There was great suspicion of "popery" and there were, of course, Catholic martyrs, killed by the Crown for their faith. It has been suggested that Robert Copley and his wife Isabella were Catholics and thus were very careful about revealing that fact.

Room 11 hosts a large, old, four-poster bed and is the largest Room in the area, offering an ensuite with a huge feature Bath. There is a tale that Copley, who was at all times careful with his money, built the upper stories of Gosforth Hall from the timbers of ships wrecked against the Irish Sea coast. These give many of the rooms a unique ambience fitting for a Building of this age.
