• RO005-014001 Settlement platform
  Description

  In 1952 drainage works on the Boyle River lowered the water level of the Lough Gara lakes, and artefacts recovered from crannogs were reported to the National Museum of Ireland. That autumn, Dr. J. Raftery and Miss E. Prendergast of the Museum staff collected artefacts from about 150 crannogs which they noted in the lakes and on the Boyle River. Dr. Raftery permitted Mr. R. E. Cross, the project engineer, to publish a map (1953) based on his own preliminary survey with numbered crannogs, a copy of which is now held in the Department of Archaeology at University College Dublin. During 1953 further drainage work on the river resulted in another reduction of the water level, which revealed numerous cairns on both sides of the river below the outlet from Upper Lough Gara. Dr. Raftery was at that time engaged in excavating crannogs at Rathtinaun (SL047-021----) and Tivannagh (RO005-012003-), but undertook in his free time to supervise an instrument survey of these additional features, which were not expected to survive and which were not properly understood. This mapped survey, from which no artefacts were recovered, is known as the Forsyth survey after one the surveyors, whose name appears on one of the finished maps. It did not necessarily include a revisit of Raftery’s 1952 preliminary survey, and where it did a natural concordance does not always occur. The Forsyth survey is retained in the National Museum of Ireland. The Raftery material was subsequently examined by Dr. C. Fredengren (2002, App. 1, 21, BOYL 001), who describes this feature (Raftery: No. 1) as a small platform, which had no artefacts associated with it. It is presently in scrub at the S edge of the river channel (Bing 2013), but it was once towards the E end of an extended Lough Gara Lower. It is not represented on the Forsyth survey.

The Forsyth survey depicts it as a cairn (diam. < 10m) with an altitude of 218.5 feet above the datum of Poolbeg Lighthouse and has the comment ‘Burnt stones’. It is also depicted as within a sub-rectangular area (dims c. 60m E-W; c. 20m N-S) defined by what are probably stepping stones or poste and backing onto the old bank at S. The cairn crannog (RO005-064----) is also within the enclosure at its NW angle c. 15m to the W. This location is currently in pasture (Bing 2013) but it was once towards the E end of a larger Lough Gara Lower. Compiled by: Michael Moore Date of revised upload: 10 November 2017
