WW2 Defensive Structure?

I located this yesterday covering a Railway Line at Portballintrae in County Antrim.

I believe it is a WW2 Defensive Structure - A pedestal for a Weapon to protect the Line.

It is similar to those I have seen at Airfields and so I am wondering if you forks can assist.

Have you seen anything similar?

For a Gun??

Any Help would be much appreciated.

An interesting find - !
I can see why it may be considered some sort of weapons mount, but there are a number of things which don't tie in with that possibility. The concrete appears to have been finished, i.e., it has a smooth finish but there are no signs of any sort of bolts or holdfasts which would be required to hold a weapon in place. The walls are much too low to be of any use, but that could have been remedied with sandbags. The quality of the casting is very poor. What does anyone make of the 'cutouts' in the visible corners of the walls - ?
This appears to have been made to mount something - but what exactly - ?:confused:

I think the Cut- Outs would have been for camouflage.

Another point that has occurred to me; why a five sided structure when a square or rectangular enclosure would have been quicker and easier to cast / build - ?

And why did this need a five sided enclosure when a square or rectangle would have been much simpler and quicker to build - ?

Nearest approximation I could locate on line.

Assume the narrow gauge railway line was a post conflict addition ?

Hi,
Thanks very much.
No - The narrow gauge railway was in use during the War and runs between Portrush and Bushmills which is interesting as there were a number of Ranges and Camps in this area at that time.
