An older Otterburn Hall existed at least as early as 1777. At that time,
Hugh Percy, 2nd Duke of Northumberland asked the hall's owner, Henry Ellison, for permission to erect a monument on the field to honour his ancestor who died during the
Battle of Otterburn. Ellison denied the request and raised a monument himself which included an obelisk, possibly an
architrave removed from Otterburn Hall's kitchen fireplace, which was placed into a socketed battle stone. This monument is open to the public by the side of the
A696 road. The present building was constructed in 1870 for Lord James Douglas on land gifted as recompense for the death of his ancestor, Lord Douglas, who fought at the Battle of Otterburn. By 1907, Sir Charles Morrison-Bell, 1st Bart., was the owner of Otterburn Hall. During
World War II, from 1940 to 1944, the hotel was used as a military hospital. The
Otterburn Training Area, established in 1911 and owned by the
Ministry of Defence, is nearby and is the second-largest live firing range in the country. In 1948, the Hall was acquired by a group of Christian businessmen who wanted to start a new venture in Christian education. By 1980, the building was converted into a hotel. The Lodge Village, now under private plot ownership, was in July 2017 being extended, adding 40 more units, in a style similar to a
caravan park layout. The original lake and island are still present within the estate, though it is now unsafe for children or teens to visit, as while the old
zip wire, landing deck and wire bridge to the island are still present, no safety warnings or barriers exist. ==Architecture and fittings==
