Settlement deserted - medieval, Castletown, Co. Laois

No walls, no foundations, no worn hollow-ways mark where Castletown once functioned as the administrative heart of a Norman lordship. The most likely location of the borough itself is thought to lie between an old motte and a church, but even that is an educated inference. There are no earthworks, no surface traces. The town, if it was ever compact enough to deserve the word, may have been what scholars call a dispersed borough, meaning its burgesses lived not in tight rows but spread across surrounding lands, loosely collected under a common legal identity rather than a shared street.

The history that can be reconstructed is, for its era, reasonably eventful. Castletown occupied the territory of Uí Buidhe, the pre-Norman Gaelic district known in anglicised form as Oboy, which Strongbow granted to a Norman lord named Robert de Bigarz before 1176. It subsequently passed through several hands: to William de Cantilupe after 1245, then to John de Hastings in 1283. By 1348 the Earl of Pembroke was drawing thirty shillings yearly from the town's burgesses, along with revenues from the hundred, a standard administrative unit of Norman manorial organisation used to manage local courts and taxation. That 1348 record is, as far as is known, the last medieval mention of the place. Castletown then vanishes from the documentary record entirely, reappearing only in the late sixteenth century under a garbled version of its name, 'Ballycashlan Omoye', when the lands were granted to John Barnyse in 1570 to 1571, then to John Baskerfield in 1578, and leased to Edward Sutton in 1590. Whether the community collapsed, dispersed quietly, or simply stopped generating paperwork is not recorded.

What survives in the landscape clusters around three related monuments: a motte and bailey, the raised earthen platform typical of early Norman fortification; a church and associated graveyard; and the levelled remains of a circular earthwork that once sat roughly 170 metres south of the church and 220 metres east of the motte. That circular feature is now gone at surface level. The arrangement of these monuments across the undulating ground is itself the only legible geometry left of whatever Castletown once was.
