Portumna
town in Co. Galway, Ireland
Portumna (Irish: Port Omna- meaning 'the landing place of the oak') is a market town in the south-east of County Galway, Ireland, on the border with and linked by a bridge to County Tipperary. The town is located to the west of the point where the River Shannon enters Lough Derg. This historic crossing point over the River Shannon between counties Tipperary and Galway has a long history of bridges and ferry crossings. On the south-western edge of the town lie Portumna Castle and Portumna forest park.
History
Portumna Bridge
Portumna is served with a five-span road bridge over the Shannon. This was designed by C. E. Stanier of London, and completed in 1911, with a central section resting on Hayes's Island which divides the river into two channels. The steel structure of the main bridge and pivoting swing bridge over the navigation channel are of technical and engineering interest, and it is the largest early-twentieth-century swing bridge in Europe. The opening section was replaced in October 2008.
The Shannon at this point consists of two channels divided by Hayes Island, the one on the County Tipperary side being about 79 m (260 ft) wide, and that on the Galway side being about 73 m (240 ft) wide. Each channel is spanned by three pairs of mild-steel plate girders, either 24 m (80 ft) or 27 m (90 ft) in length, resting on 3 m (9 ft) diameter concrete-filled cast-iron cylinders.

Why this record matters
The phrase “town in Co. Galway, Ireland” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Place names and jurisdictional language are key evidence: both can reveal earlier catalogue descriptions and overlooked record series. The source revision retrieved here is dated May 21, 2026. The linked authority identifier is Q303163. Authority coordinates are 53.089, -8.219. 2 of 2 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1911 and 2008.
A single description cannot reconcile every naming convention, rebuilding phase or administrative transfer associated with a place. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
