[2] From the window between the inner chamber and the chapel, and from other details, the date of the work is placed in the latter part of the fourteenth century, the characteristics being late Decorated.

The traditional story of the origin of the hermitage, attributing it to one of the Bertrams of Bothal Castle in this county, is told in Bishop Percy's 1771 ballad The Hermit of Warkworth.

[2] The ballad is fiction as the chapel was built as a chantry and occupied by a series of clergy from 1489 to 1536; since that time it has remained as it is today.

Warkworth Hermitage is in the care of English Heritage, who provide its only public access, a ferry boat from the riverside path below the castle.

Besides Bishop Percy's ballad mentioned above, the hermitage is the subject of Letitia Elizabeth Landon's poetical illustration Warkworth Hermitage to an engraving of a painting by Thomas Allom, published in Fisher's Drawing Room Scrap Book, 1836.
