[1] In 1330, "Roberto de Lawedre" of the Bass, described as Custodian or Keeper of the Marches and the Castle of Berwick, received, apparently upon the termination of his employment there, £33.6s.8d, plus a similar amount, from the Scottish Exchequer.

The master carpenter of Berwick, George Porter, was ordered to build 120 houses in the town, and chambers, a hall, and a lodging in the castle.

[11] The surveyor of fortifications recommended the demolition of the castle, but in October 1600 Peregrine Bertie, 13th Baron Willoughby de Eresby, Governor of Berwick, was said to have rebuilt some structures for his own use and pleasure.

George Chaworth wrote to the Earl of Shrewsbury in 1607 about its size, height, views, and good proportions and that its long gallery would make that at Worksop Manor look like a garret or attic.

[16] Large parts of the castle structure were reused as masonry in the 17th century, including for the construction of the parish church, Holy Trinity, during the Commonwealth.
