In 1334/5 Robert of Eslington had licence to crenellate his house at Eslington. The tower was held by Thomas of Hazelrigg in 1415, and was reported to be suitable for a garrison of 20 men c.1514. In 1587, the tower was stormed by the Scots under Buccleuch after the execution of Mary Queen of Scots. Nothing now remains of the old tower last mentioned in 1594.
The mansion house of Eslington Park dates mainly from the early Georgian period (post 1714) of which it is a fine example. The medieval home of the Eslingtons and their successors, the Hazelriggs, and Collingwoods, has entirely disappeared, but it is believed to have stood a short distance north of the present house on a slightly higher level in what is now the kitchen garden (Area NU 042122), where wrought stone work is still occasionally dug up. The north wall of this garden and the ha-ha east of it contain a good deal of old ashlar re-used, some of it appearing medieval. There is also built into the potting shed in the kitchen garden a simple Tudor doorway, but this was brought from Collingwood House upon its demolition. (1)

Described in the survey of 1514 as a tower with a barmkin. (2)

Lord Ravensworth of Eslington Hall had no definite information regarding the tower, but believed that it stood somewhere north of the present house. His gardener, with 56 years service has encountered no foundations in the kitchen garden (see authority 3) but has found stones in the small fir plantation to the immediate north of the house. In view of the lack of other evidence the tower has been sited to the area occupied by the kitchen garden, and the fir plantation. The stonework in the walls referred to by authority 4 appears old and well weathered but there is no evidence to show its origin or date. (3)
