History of the Dene
The first reference to Holywell Dene was in 800AD although it was then known as Merkel Dene. It was part of the Manor of Hartley.
In 1219 the Manor of Hartley was conferred to Gilbert de Laval and became part of the Delaval Estate, as it is today.
In 2000 Holywell Dene was in a bad state and deteriorating rapidly. The tenant farmer’s right to over-winter cattle in the Dene had heavily affected the ground flora and natural regeneration, as well as severely damaging the numerous paths.
Welcome to Holywell Dene!
Holywell Dene is in the South East corner of Northumberland, with a small part straddling the border into North Tyneside.
The Dene stretches for approximately 6km between the villages of Seghill in the west, passing close to Holywell and Old Hartley, and thence to Seaton Sluice on the coast in the east.
Holywell Dene is a steep sided ancient semi-natural woodland and is traversed by a small river known as the Seaton Burn. Between Old Hartley and Seaton Sluice, where the river enters the sea, the valley widens into a tidal flood plain.
Much of the Dene is part of the Delaval Estate. In 2000 the Estate granted the two Councils a 99-year lease; they in turn designated their areas Local Nature Reserves.
In the same year, 2000, a voluntary community group called Friends of Holywell Dene was established.
Flora and Fauna
The woodlands of Holywell Dene, together with its adjacent agricultural fields, support a wide variety of Flora and Fauna.
Wild flowers found, which are indicators of native woodland, include:
Bluebells in the Dene
The Fauna page of the Flora and Fauna section has been updated with a report for December.

A list of forthcoming events throughout the year.
A work party of eleven met up at 8:30 on Millfield, Seaton Sluice, to sort out the wagonway steps above the Pipe Pond. The weather was fine, if cold. I think the sun went in while we were working, but we were too busy to notice....
A small but perfectly formed work party of eight assembled at the Hartley Lane carpark for a morning of miscellaneous jobs on a mild day with a bright sun shining at a very shallow angle. The ground underfoot was generally wet, but there was frost and ice in sheltered places....
A work party of 10 gathered at Crowhall Farm on a winter’s morning to tackle the branches in the river that were left over from the 28th November. After a 10 minute walk we reached the area – between the embankment tunnel and Holywell road bridge – and were split into two teams....
A work party of seven turned out for a “warm up” session for the new year which started at 9:00 and was rained off at 11:00. The weather was uninviting: dull and cold, with the ground partly frozen....
A work party of nine volunteers assembled at the metal gate on the Hartley West Farm road at 8:30 for another session of winter footpath maintenance. The conditions were far from inspiring, with an unbroken blanket of cloud overhead and very damp conditions underfoot ...
