Bridge

The National Monuments Service's description

Road bridge aligned NW-SE traversing the Delvin River flowing from S to N which forms the county boundary between Dublin and Meath, connecting the townland of Coolfores with Tullog, Co. Meath. The river at this location also forms the parish boundary between the parish of Stamullin, Co. Meath and the parish of Naul, Co. Dublin.   Tullog (Tullock) flour mill which stood on the site of an earlier corn and tuck mill (ME034-008-) from which the bridge was named, immediately W of the bridge. The ‘old mill of Tullock’ was described as forming part of the N boundary of the townland of Reynoldstown (Simington 1945, 34). Present single-arched (Wth 4.9m x H 1.7m) road bridge described by the NIAH as; ‘Single-arch rubble stone road bridge, c.1850’ (NIAH Reg. No. 11303001). This 19th-century stone bridge may have been built on the site of an earlier bridge contemporaneous with the medieval mill of Tullog. The ‘Old Mill’ of Tullog and the road traversing the Delvin River is depicted on Rocque’s 1760 Map of County Dublin.

The Historic Road Bridges Survey commissioned in 2008 by Fingal County Council described this bridge as a; ‘Single segmental-arched, stone-built road bridge over Delvin river on Fingal/Meath border beside old mill building which has been converted to residential use. Punched ashlar limestone voussoirs with roughly coursed rubble stone spandrels and parapets with some remains of lime render to south east corner. Some corbel detail beneath vegetation on parapet at this corner which may have supported further parapet detail but close examination not possible. Dry stone-built south west bank abutting bridge. Coping either not extant or not visible due to excessive vegetation.  This well-constructed stone bridge appears early-mid nineteenth century in date based simply on its good condition (despite damaged parapet wall tops), although it may be earlier or be a replacement for a previous structure on the site as the mill here is older. Located on a very quiet road with relatively little traffic using it, it is a structure of local significance with historic interest.’ (Cronin et. al. 2008, Bridge No. 2, 19-27).
