Nature and heritage
Designated sites and recorded monuments
Designated sites
No designated site (Special Area of Conservation, Special Protection Area, Natural Heritage Area or proposed one) touches the townland of Coolmine.
Recorded monuments
- DU013-011 Designed landscape - tree-ring
Description
This site is marked as a tree-covered mound in the 1837 OS 6 inch map, one of a line of such mounds which bordered the northern end of Coolmine estate. It was removed during land reclamation in the late 1950s and appears as a continuous circular cropmark on Cambridge photography (CUCAP AP1 27). Excavations in advance of the Navan Road Improvement Scheme in 1989 identified an enclosure (26m diam.). It consisted of a ditch (3m w. x 1m d.) that contained post medieval delft and clay pipe and was interpreted as a tree ring.

- DU013-019001 Church
Description
There is a raised oval area (dims. L 50m E-W, Wth.30m) formerly within the grounds of Coolmine House. According to Healy there were human bones exposed on the site (1974, 21). Traditionally associated with St. Machtus and believed to be the site of the 'white chapel' which went out of existence about 1490 (Ronan 1940, 188). In the list of the churches of the dioceses c. AD 1275, the Crede Mihi, the church of 'Culmyn' is mentioned. It is also mentioned in the Taxation of 1292 and 1294. Now contained within the Blanchardstown Millennium Park. The site was subject to geophysical survey (Licence no. 09R195) in advance of the proposed Metro West. Remains of enclosure ditches and possible pit type features associated with the Coolmine Church (DU013-019001-) and graveyard (DU013-019002-) were identified. A sub-circular enclosure (c.50m diam. NS) and further ditch remains extending to the south and east were associated with possible burnt/fired features which may indicate hearths or kilns (Nicholls 2009, 14). A dog run was instated directly abutting the eastern limit of the oval area without archaeological supervision.
