Pele Tower.

Sited above Old Jedworth town, the tower has extensive views in all directions. Mervinslaw Tower is adjacent to an ancient woodland which included oak trees that may have been planted by its owners. Originally there were additional buildings alongside and around the tower.

On the east are the steep banks of Edgarstone rivulet, and on the south west the swampy ground ascending into Carter Fell (Jeffrey, 1855).

The structure consisted of two storeys, is oblong in shape measuring 7.7m by 6.5m, with the walls being 1.2m thick. The remaining walls stand to a height of 5.48m. The entrance was located at ground floor level to the south east, but there was also an entrance, via a ladder or wooden staircase, to the south west. With this in mind, and the above quote by Jeffrey placing it within its landscape, you can see the perfect siting of this tower for defence and security for its owners and occupiers. Although dating from the sixteenth century, the lands were significant in the history of Scotland.

There is hardly any written and documentary evidence for the site, however, it is associated with the Riddell/Ridel family and they were very prominent, especially during the reign of William I of Scotland. The family originated from Normandy with their ancestor Sieur de Riddell who came over to England in 1066 with William I, the Conqueror.

My own opinion is that the pele tower was most probably built by Baron Andrew Riddell, or his father Walter.



Archaeologically the only information I have managed to find relating to the site, and its area was a sword pommel discovered in 1977. It is believed to be of Medieval date and may possibly have connections to the site, however, there is no evidence that it has – so I will leave that one up to you to draw your own conclusions. Also, within the area, has been uncovered the top of a flagstaff which was stone and plated with bronze.
