Island Gazetteer

Advanced find

The list of islands and their jurisdictions is extensive, so much so it is on this separate page. There are over 5000 islands making up the British Isles, stretching from the Faeroe Isles to the Plateau des Minquiers.

This may be helpful and then again it may not. It is best used by using the automatic-search function on your Browser to find the placename your are looking for and going from what you find there. All variants, alternative names, and localities are listed, so you're bound to find something.

Uninhabited islands and wildlife reserves generally not mentioned.

There are lot of small islands, the greater number in the smaller.
I'm just glad I'm not a Norwegian Cartographer, that's all.

Advice for North Americans: The British Isles are 32 times smaller than the USA, but contain only a quarter as many people, making them 8 times more densely populated, so don't ask the English abroad if they've met the Queen, okay? Have you met the President? If you want a rural-dominated landscape with lots of greenery, visit the Irish Republic.
Certainly don't drive over minor country road junctions without looking, as one tourist couple did, assuming all Britain was like the idyllic backwater they found themselves in at the time. At the first main road they crossed, they were squashed flat by a large truck. True story. So beware of your assumptions. And be careful.

Definitions: Islands, Islets, Rocks, Rocklets, etc

What you define as an island or a community is very much subjective. Some points disappear at high tide and others are only large enough for a single seagull. Do you count these? I don't here.

What's a community? An inhabited place, clearly, but one individual is not a community, not even if they have schizophrenia.

A small crew of a vessel, or a small company of a dozen or so, or even a fairly large transient population may not be a community. Even when there is a community of people, they may not be big enough to host a prison/police/garrison/whatever.
Small crews will have brigs and the power of citizens' arrest, and will fumble along like that until they can send for help. Maritime Law, quiet literally a law unto itself, can come into play under some circumstances. Some other vessels are run by the military, and have their own rules (and guns!). Gun ownership on remote outposts is less frowned-upon as on the mainland, even if it is largely aimed at the local wildlife.

Aswell as all that, the outposts that support them can (and do) include the following:

These may be off-shore of the larger islands, joined by a bridge, causeway, narrow strip of land, pipeline, or exposed mudflats at low tide.

Some may be further out, the most remote, Rockall, being 220 miles away from any other British landmass (, or any landmass at all, for that matter.

Some may move. Hopefully these are only the artificial ones.

Many small islands are privately-owned, by companies and individuals. Most have British or Irish Sovereignty, but a few are partially or fully independent. The IOM only replies on the UK in matters of Defence, for instance.

Divided we Stand

Notes on Politics

Irritating questions arising from avoiding the Political British territory and all that stuff:

The British Isles have also variously been called IONA (Islands of the North Atlantic), and These Islands, but neither of these terms really help, and if somebody's going to misinterpret a geological term as a political one, then get offended about their own mistake, that's their own problem.

Notes about Geographical Extent

The Faeroe Isles, along with Rockall, are part of the Rockall Rise, which are associated with the British Isles, but distant also.
It is debatable whether they are in or not, but here I assume that they are. The rest of the Isles are on the European Continental Shelf; The Rockall Rise is not part of the shelf proper, but it's sort of merged into it.

Extending it further, does this include Iceland? No. Iceland is geographically part of Greenland. There is a deep basin separating it from the Rockall Rise.

So really these are North European Western Islands ("NEW Islands"(?)). Presto! [Accidentally] another IONA. Nuts.

Massive Islands

The large one on the right is Great Britain, and the smaller one on the left is Ireland.

The British Mainland

Irritatingly, this seemed to no name, and is the larger of the main islands on the east. It contains Scotland, England, and Wales. I call it the Sceptred Isle; Shakespeare.
Note that Great Britain is not a country, but a landmass; Britain is the country. This means Britain is bigger than Great Britain.
It contains 157 state prisons.

Notes about Scotland

Scotland is a British province occupying the northern third of Great Britain.

A straight line drawn between NI, Northern Scotland, and Norway, reveals a similar fragmented geography.
This seems to be something to do with northern glacial retreat during the last ice age, and these places being near the edge of the Continental Shelf.

The proper Scottish islands fall into two main groups: The Northern Isles (Orkneys and Shetlands (over 100)) and the Hebrides archipelago (Inner and Outer, around 500).

Splitting the Scottish Highlands down the middle between Fort William and Inverness is the Great Glen, consisting mainly of Loch Ness. The gaps are joined by the Caledonian Canal, effectively creating a hidden island.
The Crinan Canal cuts off the Kintyre peninsula in a similar fashion, between Jura Sound at Crinan and Loch Fyne at Lochgilphead.

The Island of Ireland

I thought this had no name either, largely thanks to the split personality of Northern Ireland and Eire. I call it the Emerald Isle, but infact it is simply called Ireland, with the poetic name "Erin"
- As distinguished from Ēire (Ireland in Irish), which is the country of Ireland, which is not Ireland although it is contained within it: Who think's up this stuff?
Ie, Ireland is a landmass, not a country. The Republic of Ireland or Southern Ireland is, and so is Northern Ireland or NI. Southern Ireland is never called SI, and extends further north than Northern Ireland. I wish I hadn't started looking into this.
It contains 17 state prisons.

Significant Islands and Island Groups
