Bentra Golf Course is in the seaside town of Whitehead on Northern Ireland's Antrim coast.

Many of the golfers hacking through the rough today will be unaware that this was the site of the first airship mooring station in Ireland.

Photos from the time show strange cigar-shaped apparitions floating silently above the rural landscape of fields and ancient stone walls.

Air crews flying from Bentra, along with its sister station at Luce Bay in Scotland, played a crucial role in protecting shipping in the North Channel from German submarines, or ‘U-boats’.

In February 1915 U-boats (Unterseebooten) were turned against merchant ships supplying Britain. This was after some German successes against British warships, and in response to the increasingly tight British naval blockade preventing vital supplies from reaching Germany.
