Source-derived summary

Cannon Rock is a skerry in the North Channel off the coast of the Ards Peninsula near Cloughey, County Down, Northern Ireland. It is the easternmost point of Ireland. Cannon Rock is east of South Rock, on which there is a disused lighthouse.

Marine hazard

The rock is a hazard to shipping. Between 1861 and 1865, nine vessels ran aground on it.

Editorial summary

Begin with the source’s own compact description: “Cannon Rock” is island in Northern Ireland. The dossier treats that line as a proposition to test through Cannon, Rock and island, not as a finished interpretation.

Editorial reviewA valuable geographic starting point for tracing changing names, boundaries, uses and administrative responsibility. The current lead gives the account dated anchors—1861, 1865—that can be checked directly. The selected authority fields contribute no independent date. For this dossier, Cannon, Rock and island is the immediate research focus.
Editorial analysis

Why this record matters

The phrase “island in Northern 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.

Evidence profile

Maps, plans, fabric surveys and administrative records can establish how the site’s name, extent and function changed over time. The source revision retrieved here is dated Sep 23, 2025. The linked authority identifier is Q5032790. Authority coordinates are 54.408, -5.367. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank. The first chronological checks are 1861 and 1865.

Critical limits

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.

How to read it

Treat names, boundaries and functions as historically changeable. Maps, plans, inventories and administrative records can clarify what the place meant at different dates.
