Minerex Geophysics Ltd. (MGX) carried out an archaeological geophysical survey on the route of the proposed N18 Oranmore to Gort Road Scheme. The project was carried out in co-operation with Eastern Atlas Geophysikalische Prospection and Moore Archaeological & Environmental Services Ltd. 2. The phase 1 survey consisted of a magnetic susceptibility centreline survey with 10m station spacing over a length of 27.52km. 3. The phase 2 survey consisted of 14 detailed magnetic susceptibility areas and 40 detailed magnetic gradiometry panels at a total of 29 locations ( 6 locations for magnetic susceptibility and 23 locations for magnetic gradiometry). Each area had a nominal size of 0.25ha (50m x 50m). At some locations more than 1 panel was carried out. 4. The main objectives of the survey were to identify archaeological sites in preparation for a programme of test excavations and to provide targeted locations for excavations. 5. The results of the survey are displayed on tables, figures, maps and plates. 6. An interpretation has been made and 29 locations have been grouped into categories of high, medium and low archaeological potential. 7. It is expected that the four areas marked as high archaeological potential will yield archaeological finds that will have to be fully excavated prior to commencing construction of the road. 8. Six recorded monuments on the road scheme were targeted in the survey and it is interpreted that three will require excavation (a burnt mount, a well and a ringfort) while three are not on the roadtake or are not archaeological features. 9. Two other areas interpreted with high archaeological potential are expected to be a ringfort at CH17000 and linear or circular features near an existing tomb (CH6600). 10. One medium potential area on the roadtake is located near an unrecorded ring fort that is beside the roadtake at CH9950. 11. A large visible circular feature at CH 9850 should also be tested. 12. The areas marked as high archaeological potential should be tested as early as possible in any future excavation programme in order to gain a maximum of time for the full excavation.Primary Archive held by Galway NRDO.
