Recorded monuments

• WI010-018 Ringfort - rath
  Description

  Situated on a gentle W-facing slope overlooking marshy terrain. Bivallate circular ringfort (diam. 23m; max. ext. diam. 41.5m) excavated prior to the construction of the Blessington Reservoir. The site was defined by an earthen bank (Wth 1.5m; H 0.6m) and a fosse (Wth 2.4m; D 1m) with an outer bank (Wth 2.7m; H 0.6m) from SSW-NW-NE. The fosse was separated from the inner bank by a berm (Wth 3-6m) and was partly separated from the outer bank by a second berm (max. Wth 3.4m). There were two narrow gaps (Wth 1m) in the inner bank at the NE and WSW with a more substantial example (Wth 1.5m) at the SSE opposite a causeway in the fosse. A second causeway formed by large stones occurred at the NE but may not have been an original feature. At the S, an L-shaped bank ran from the inner bank outwards across the fosse and then continued eastwards as far as the SSE entrance. Little, other than an arc of irregular paving in the N sector of the interior, was revealed during excavation.

  Description

  Detached three-bay two-storey house, with distinctive granite porch, built c.1875. To the west there is a single-storey extension of c.1985. The façade is finished in unpainted lined render with window surrounds, eaves brackets, and the porch is all in granite, whilst the extension is in brick with large areas of glazing. The hipped roof is slated and has granite chimneystacks with corbelling. The entrance consists of a panelled timber door with cornice-like entablature on console brackets and segmental fanlight with rope pattern archivolt. The entrance is set within the decorative granite gable-end of the porch, with gable itself shaped in a vaguely Dutch fashion and topped with a finial. The windows are flat-headed and have two over two timber sash frames, while the surrounds to those on the ground floor have distinctive curved ‘heels’ and an entablature, with similar heels and keystone to those on the first floor. Cast-iron rainwater goods. The building is set side on to a lane leading to a quarry, but is surrounded to the north, south and west by a garden enclosed with semi-coursed rubble walls with a carriage gateway to the north with square granite piers topped with pyramidal caps with ball finials. Within the garden is the remains of another enclosure, with simple wrought-iron railings and slender granite piers with pyramidal caps and ball finials (many now broken off).
