Antrim and St Patrick’s Church. 1 1.2 Location of excavation area to the north of St Partick’s Church, Armoy, Co. 3 Antrim showing the grid sub-divisions employed during the excavation and the principle features uncovered. 2.1 Location of SMR sites which may relate to Early Medieval to Post-Medieval 22 activity close to St Patrick’s Church (ANT 013:010). 3.1 The extent of the excavation trench (delineated by dashed line), to the north 26 of the present St Patrick’s Church, Armoy. 3.2 Features which represent Phases 1, 2 (the ditch cut), 3 (primary ditch fills 30 and gullies) and 4 (ditch recut and primary fill). The plan shows the main ditch (C103) with its scarped walkway to the north, and parallel gully to the south. The possible termination of the Phase 2 ditch cut is represented by the dashed red line and the section points (A and B) for Figure 3.3 are marked. 3.3 Section of the ditch (C103) showing fills and also schematic representation 37 of Phases 2 to 8. Section points A and B are shown on the ditch plan Figure 3.2. 3.4 Section drawings showing (A) grids C-D southern baulk: north facing section; 43 (B) Southwest grid southern baulk: north facing section; (C) between Southwest grid and grid C: west facing section. Section includes C201 which represents Phase 5 activity. For location of grids see figure 1.2. 3.5 Plan showing the excavated features which represent Phase 6 activity at 44 Armoy. 3.6 Plan showing features representing Phase 7 (souterrain construction) and 55 Phase 8 (occupation remains including use of souterrain and metalling and schist paving and hearth). 3.7 Plan of the souterrain (C229). The section points for Figure 3.8 are marked 56 as points A to O. 3.8 Sections of souterrain (C229) showing surviving structural profiles. Section 58 points A to O are shown on the souterrain plan (see Figure 3.7). 3.9 Plan showing features representing Phase 9, including two phases of 67 construction of a rectangular structure (Phases 9ai and 9aii) and remodelling of the souterrain. 3.10 Distribution of burials uncovered during the excavation, representing Phase 76 10 activity. 4.1 Location of 2005 survey at Armoy. 91 4.2 Topographical survey of the mound at Armoy. 93 4.3 Features recorded on the summit and slopes of the mound. 94 4.4 The knoll and field boundaries. 96 4.5 Survey Area. 99 iii St Patrick’s Church, Armoy, Co.

Antrim CAF DSR 44 1 SUMMARY 1.1 Background 1.1.1 The archaeological investigations at St Patrick’s Church, Armoy, Co. Antrim (Irish Grid Reference D 0778 3325), focused on a small field or paddock, immediately to the north of the 19th century church and round tower (SMR: ANT 013:010; Plate 1 – cover; Fig. 1.1). The field measures 30 to 45m (north-south) by 50 to 65m (east- west), and lies just 50m to the north and west of the Wellwater river at an altitude of >30m OD. The field carries a low gradient, rising gently towards the north, with the area for excavation measuring c25m x 35m at the widest points.
