Old Kilpatrick (Scots: Auld Kilpaitrick, Scottish Gaelic: Cille Phàdraig meaning "Patrick's church"), is a village in West Dunbartonshire, Scotland.

The route was surveyed during the 18th century, and traced to the Chapel Hill,[7] where various Roman artefacts were found.

In 1923, during redevelopment of the area, significant archaeology was undertaken which established the size and nature of the Roman Fort.

[20] The fort, built around 81 AD, occupied an area of about four acres and was enclosed by an outer defensive wall.

If the date is correct, it shows that the fort preceded the Antonine Wall by some sixty years.

[28] It was found at Ferrydyke on the Clyde's northern bank[29] and records the completion of 4411 feet; the last 3 Roman numerals are the same as the remaining ones on the other damaged distance slab (RIB 2206).

[35] The inscription mentions the First Cohort of Baetasians, previously known to have been at Bar Hill, and also a centurion from The First Legion (Italica).

One known artefact, a remnant of the previous medieval church, a font is currently on display in the local museum.

[36] Unusually in this part of Clydeside two examples of the Govan School of sculpture, dated to the Viking period, have been found.

Eventually the lands were conferred on Claude Hamilton (a boy of ten), founder of the Abercorn family.

It was more common for new parishes to have "daughter" status, with wealth retained by the central, or cathedral church.

[55] A fire in August 2015 saw the RC congregation temporarily without a place to worship, taking up the kind offer of the nearby Church of Scotland congregation to use their building, a friendly act of ecumenism in part of Scotland traditionally torn by bigotry.

[56] There are plans to develop a marine technology hub at the former Royal Navy oil refinery[57] and a wooded community area near the village.
