Two small earthworks to the east and west of the castle have survived to the present day, and may represent siege-works built for the campaign.
[2] The walls were raised, the gatehouse remodelled and other buildings were constructed on the site, including a substantial block, possibly a lodgings range, within the inner bailey.
Roger had succeeded his father Edmund in 1304, and strengthened the position of the Mortimer family considerably, acquiring Ludlow Castle and many lands in Ireland through marriage to the heiress Joan de Geneville.
In 1381 their son, Roger, inherited at the age of six and was declared the heir presumptive should Richard II (Phillipa's cousin) die childless.
Richard's son Edward, Earl of March was almost certainly based at Wigmore Castle before his victory at the Battle of Mortimer's Cross in 1461.
By the 20th century neglect and the growth of vegetation had left the remains of the castle as a scattering of ruins with features such as towers, curtain walls and the gatehouse almost indiscernible.
Unusually, because it remained in private hands, Wigmore was not subject to the large scale clearances carried out at most other major historic sites in the late 19th and early 20th centuries.
In 1995 Wigmore Castle came into the guardianship of English Heritage, which carried out some conservation work and small-scale excavation, making the site a little more accessible to visitors.
[4] The castle was of great strategic importance as it lies almost halfway between the rivers Teme and Lugg (about 4 km from each) and commands the wide area between them.
