Ireland uses distinctive green bollards. (by Geotips )

Public post boxes are also green. China and Egypt share the colour, but they lack widespread Street View and the scenery differs greatly. Box shapes vary across Ireland.

You will encounter many ⚠️ warning signs. Irish versions often omit the person, whereas the UK frequently shows a figure inside. If you see the figure, consider the UK; without it, Ireland is more likely. (Reference illustration is homemade!)


Still unsure between Ireland and the UK? A yellow dashed centre line strongly points to Ireland. (参考文献 World map lecture digest (Japanese)) A yellow stop line instead suggests Jersey.

Road numbers begin with R, N, or M. The UK uses B, A, or M prefixes instead.

Narrow down state/region
- In stony regions you will find dry-stone walls (from Wikipedia 『Dry stone』)—especially across the west near the Burren and along the nearby coast

Narrow down city/town
- On Inishturk and nearby islands you can spot a vivid red lighthouse
- Inishbofin features fort-like ruins that stand out (参考文献 Inishbofin)
- Large oil storage tanks or container terminals suggest checking Dublin
The island’s official tourism site highlights tourism as the main industry. Look for fortress-like structures reminiscent of ruins.
