- LI024-074: Designed landscape - folly, https://heritagedata.maps.arcgis.com/apps/webappviewer/index.html?id=0c9eb9575b544081b0d296436d8f60f8&query=18a4b61b268-layer-9%2CSMRS%2CLI024-074----. On steep NNE-facing slope, on the demesne lands of Derk House which stands 360m to SSW. A circular tower or folly (LI024-075----) stands 100m to SSW. Not depicted as an antiquity on any edition of the OS 6-inch maps. Depicted on the 1897 ed. OS 25-inch map as a subcircular-shaped tree-planted enclosure. Surveyed by the ASI in 2008 and described as a circular-shaped area (diam. 12m) enclosed by intermittent traces of a low earthen bank (Wth 2m; int. H 0.75m; ext. H 0.17m) from ESE-S-W reduced to a scarp (H 1.35m) visible from W-N-E-ESE with traces of a possible fosse at SW. The interior has a steep NNE-facing slope and there is a large conglomerate boulder (H 3m) in the N quadrant. The interior and bank are planted with Beech trees. Probable tree-ring of Derk House demesne. Monument is visible as a roughly circular-shaped tree-planted earthwork Google Earth orthoimage taken 28/06/2018.

In a small coppice of mature Beech trees, on the demesne lands of Derk House which stands 275m to SW, with excellent views from NNW-N-E-S. Tree-ring (LI024-074----) lies 100m to NNE. Annotated 'Tower' and depicted on the 1897 ed. OS 25-inch map as a circular-shaped building. Surveyed by the ASI in 2008 and described as a three-storey, circular-shaped, roofless tower constructed of rubble stone. The ground floor has a base batter and the brick around the top may have formed crenellations. The ground floor door opening has a segmental arch of brick and this style is carried through to the window openings. The walls are rendered on the interior and on the exterior. The interior is hollow, however it has a fireplace opening and a flue in the rear wall, opposite the ground floor entrance. Multiple window openings would suggest that this tower was built as a folly on the demesne lands of Derk House. Monument is obscured by mature trees on Google Earth orthoimage taken 28/06/2018.

Within a cluster of barrows (LI033-036001-/009-; LI033-090/091-; LI033-121/122----; LI033-154----) concentrated in the S half of Derk townland. Not depicted on historic OSi maps. Identified by Bruff aerial photographic survey in 1986 (Bruff 75; AP 4/3626) as a series of rectilinear enclosures. Visible as a pattern of rectilinear cropmarks, some perpendicular to each, located within four fields (400m NW-SE x 250m NE-SW) visible on OSi orthophoto taken between 2005-12 and on Google Earth orthoimage dated 20/09/2020. Linear cropmarks appear to be the remains of drainage ditches rather than a pre-1700 field system.

Everytownland reads the registered freehold land and the statutory boundaries of Tailte Éireann, the national zoning, planning file and heritage records of the Department of Housing, Local Government and Heritage, and the Residential Property Price Register. A parcel is the land of a title, not an address. The owner's name is in the Land Registry of Tailte Éireann: a copy of the folio can be ordered on landdirect.ie, for a fee; this site names no owner. A price is the price recorded for a past sale, not a valuation.
