How to use the Planning Map

This bunker planning map shows all UK bunkers, it can be used to determine which bunkers have been activated, by and when, and also to show which bunkers are UKBOTA ATNO (‘All Time New Ones’), i.e. there is no record of a previous activation at this bunker. Note, this map is probably best used for planning an activation, for use during an activation we recommend the activation maps linked below. For clarity bunkers are shown as ‘hot spots’ until you ‘zoom’ in at which point they will be shown individually.

Controls:
* Select to view by year or Lifetime, ie. ‘All Time’
* Toggle Map / Satellite View
* Show bunkers activations and un-activated bunkers (ATNO)
* Show 1km range circles

Statistics: Show how many bunkers have been activated. Find: Search for a bunker (use the correct syntax!)

ℹ️ Note: To view your personalised Activator and Hunter maps, please log in to Bunkerbase 2 (BB2) first. Once logged in, your maps will appear on your Activator and Hunter dashboards.

Activation Maps

📍 The above map is great for planning. Whilst activating we recommend either the the M1SDH map (great for multi-scheme activations, eg. if activating UKBOTA and POTA at the same time), or the WWBOTA map. Both the M1SDH and WWBOTA have the added bonus of geolocation of your actual activating location.

Google Map Overlay

📍 A Google Maps compatible file of current UKBOTA bunkers as a KMZ file can be found in our downloads area here.

Disclaimer

⚠️ Safety and Right of Access. Inclusion on our list does not mean that a bunker, including anywhere within the activation zone is either safe or legal to access. If in doubt activators are advised to seek permission from the landowner and conduct your own Risk Assessment. You are advised to follow all local signage regarding permissions, access, safety and site photography.

UKBOTA accepts no responsibility for issues arising from an activators activity.

Tips for using the Bunker List

💡 How to propose new bunkers for the UKBOTA list. The UKBOTA list is updated 3 or 4 times a year, proposals for the list are developed collaboratively on the UKBOTA WhatsApp channels. See UKBOTA WhatsApp (link on homepage) for details.

How to list more than 10 bunkers

ℹ️ Change to value to more than 10 (or show all) using the show x entries feature top left. Alternatively the pagination feature (bottom right) will list the bunkers 10 at a time.

How to print the list or download it as a PDF or CSV file

ℹ️ Use the icons on the top right of the table. Note: To print or download the full list you must first Show All entries (see above).

How to find a particular bunker by the UKBOTA Reference Number

ℹ️ Type the bunker reference in the filter box below the UKBOTA Ref column. Note: If you type B/G-0001 it will only show B/G-0001, but if you type 0001 without the B/G- part it will list all UKBOTA bunkers with a 0001 reference, eg. B/G-0001, B/GM-0001, B/GI-0001 etc. Alternatively the reference can be typed in the (global) search top right, but note if you type 0001 it may also return other data containing 0001 such as a bunker with a latitude like 51.0001!

How to find a particular bunker by the name

ℹ️ Type the bunker name in the filter box below the Name column. This filter box will also find partials names, eg. type 'York' and it will show 4 bunkers: 2 containing the word YORK and two YORKshire Alternatively the name can be typed in the (global) search top right.

How to find a bunker of a particular type or in a particular area etc

ℹ️ See the tips on bunker names and references, the filter and searching works in the same way

Compound filtering

ℹ️ The table list can conduct complex compound searches by entering filter data in more than one column, e.g. Enter 'ROC' in Type and 'Essex' in Area and it will show all 87 ROC bunkers listed in Essex (or only 10 if it is still setup to show the first 10 entries - see the first tip)

Sorting by column

ℹ️ By default the table list will sort by UKBOTA Ref first, i.e. B/G-0001, B/G-0002 and so on. The sort order can be changed to ascend or descend on any column data by click the small triangle next to the column name.

A note on coordinate accuracy

We strive to plot UKBOTA bunkers as accurately as possible. However, sometimes the data we receive is incorrect or based on low-fidelity grid references (for example, a 6-figure grid reference can be up to 100m out in any direction). If you have any updates that more accurately locate a bunker, please let us know.

Worked all Britain (WAB) Squares

⚠️ A note on WAB Squares. The WAB square listed is the square the bunker is centred on. UKBOTA bunkers have a generous 1000m (1km) ‘activation zone’, i.e. they may be activated within 1000m radius of the given bunker coordinates. This may mean that the actual location an activator is activating from may not be the same as the WAB square listed. Do not assume that the activator is in the square given on our list.

This images below (Google Earth) illustrate the challenge regarding WAB squares!

The image is centred on B/G-0848 (the ROC Post at Rye Harbour on the South Coast).

As can be seen the activation zone (blue 1000m radius circle) covers 4 WAB squares: The bunker is listed at TQ91, but the activator could be in TQ82, TQ92, TQ81 or TQ91 (as shown by the 4 yellow triangle examples).

ℹ️ For information related to WAB Squares and awards we recommend a visit to their website here.
