[Closed] Meaning of"AL" on OS map?

Alien Landing sites

Access Land?

(complete guess)

The purple boundary means Access Land. They have symbols to indicate who owns or manages the access land, FC, NT, etc, but maybe none are appropriate so they just use AL?

Got it. It is Access Land. Google spews up the 25k key but it's the 50k you want.

Access Land?

I wondered the same thing, but the area should have a yellow 'wash' if it is consistent with other maps.

So why is the "access land" only on those small, isolated tops?

Doesn't make much sense to me?

Check with this?

They may be areas owned by someone other than the rest of the land to help preserve them. English Heritage as they’re the Iron Age forts.

Just have. The just about the whole area is designated access land. Way more than on the OS map.

peterno, from area 51, seems to know

Looks like they've all got ancient monuments within the bubbled. Maybe access land to allow you to legally stray off path to see these sites?

They look like hill fort sites to me. I'm guessing that they might be scheduled as ancient monuments or similar, and have restrictions on cultivation and/or different ownership to the surrounding farm land.

Edit: Must type faster!

When did they change from yellow wash to purple borders for access land?

Yup correct TomD hence the orange dots.

Yep, both Great Hetha & Little Hetha have forts, t'other one has a homestead. So as said ancient monuments and/or of archaeological significance.

Recently? I found a comment in the corner of the Internet from 2019 saying they were "new."

Orange dots connecting are ‘permissive footpaths’ which means the right of way can be revoked by the land owner (green paths are absolute).

just about the whole area is designated access land. Way more than on the OS map.

Because of this, I suspect that the AL must denote different ownership to the surrounding access land (rather than access land per-se).

Difficult to tell from the isolated map section, but it appears that the larger area may have the normal (for 1:25k) yellow background.

That symbol isn't present on the online version of the map (available with a subscription), which I assume to be the most up to date.
Great Hetha and the homestead are in access land (indicated by the tan shaded boundary line in 1:25K), little Hetha isn't.

I was wrong about the purple border for access land - that's on the 1:50k, the 1:25k is the tan border. Interestingly, on the online version (as sgn23) in the areas of access land, the permissive footpaths all stop at the point where the purple circles were; my guess is the permissive paths were designated when the hilltops were access land but the rest wasn't.

Both the size of the access area has changed and the OS legend. These screenshots are from my OS Maps account - so the latest version of the map. Note the "permissive footpath" up to Little Hetha.
