• OF007-050 Crannog
  Description

  Situated on flat poorly drained land, on the floodplains of the nearby river located 200m to the W. Circular flat topped area (diam. 19m) enclosed by a wide fosse with no evidence of an outer bank or entrance feature. Field drains run off the four sides of this area which has natural bedrock protruding. Site may be non-archaeological and may have been formed when digging the field drains which decided to go around the natural bedrock rather than dig through the rock thus forming the circular area. Described in 1977 as 'a small circular enclosure surrounded by a shallow fosse. The fosse on the NW side is very poorly preserved & can only be traced with difficulty. There is no trace of a bank around the interior. There are slight remains of an outer bank on SE & SW. This however appears to be a result of deepening the fosse on these sides. The interior has very slight rises & hollows, but no definite features which might be of archaeological interest. Field drains run into the fosse on North, South, East & West. This site does no immediately resemble a ringfort and it is difficult to say what type of monument it is. It is approx. 19m in diam. E-W & 19m in diam. N-S. It is set in flat pasture land which is moderately drained. Some large boulders lie on the edge of the interior on the inside of the fosse. Other boulders lie in the adjoining field perhaps this is an area of rock outcrop. Possibly it is the site of a crannog' (SMR File 1977). Only the S half of the site is indicated as a curving field boundary and not as an antiquity on the 1838 edition of the OS 6-inch map. This curving field boundary may be the result of land reclamation works. Alternatively if it was an archaeological monument, this feature may represent the remains of a levelled crannog. The land in which the potential monument is located was wet marshy land that appears to be a floodplain and is marked on the OS 6-inch maps as 'The Rushes'. The above description is derived from the published 'Archaeological Inventory of County Offaly' (Dublin: Stationery Office, 1997).

• OF007-051 Castle - unclassified
  Description

  Situated on a slight rise in undulating countryside. Only a portion of the N wall survives with wall footings elsewhere. The N wall measures 4m high, 5m long and 0.9m thick, with evidence of a chimney flue at W end of N wall. No other architectural features evident. Possible 17th-century date.

• OF007-051001 Bawn
  Description

  Possible bawn area located around Castle Wetherall of which partial remains survive incorporated into laneway to the S and SE of the castle (OF007-051). This old laneway leads down to the medieval Deerpark which is now a townland defined by a stone wall which may be the original enclosing element around the deerpark. On the first ed. OS 6-inch map there is a small circular building incorporated into the lane way to the E of the castle. This building may have been a flanking tower of the bawn wall that enclosed the castle. Today the wall of the laneway kicks out indicating the line of this levelled tower. Compiled by: Caimin O'Brien. Date of upload: 23 May 2011

• OF007-052 Burial ground
  Description

  Situated on a slight rise in undulating countryside. A large irregularly shaped graveyard (dims. 68m N-S x 41m E-W) enclosed by a drystone wall with 18th and 19th-century headstones concentrated in its S sector. There is a stile and coffin stand in the centre of the graveyard wall facing onto the road on the N side of the graveyard. A small rectangular drystone-walled enclosure (int. dims. 8m x 8m) in the SE quadrant may represent a single family burial plot. There are no visible gravemarkers inside this small enclosure which is accessed via a stile which is visible in the centre of the E wall of the enclosure. Two bullaun stones (OF007-052001/002-) are located in a pile of field clearance stones to the N of the headstones. A chamfered and rebated jambstone of a late medieval limestone window can be seen lying on the ground immediately N of the headstones. This fragment may have come from the nearby castle ruins (OF007-051) located in the field to the SW of the graveyard. There is a lot of rock outcrop within the graveyard and there is no clear evidence for any church site within the graveyard.
