A First World War German 105 mm leichte Feldhaubitzer (light field Howitzer), badly corroded in parts, placed on a hill and secured in concrete after the war as a memorial.
This trophy German Light Field Gun was placed on the hilltop at Twyn-y-garth, near Llandeilo Graban, in January 1920 in memory of those from the area who died during the war, especially Christopher Williams-Vaughan whose sister Mrs Lionel Trafford ordered it from the War Office. The gun had fallen into disrepair by 1999 but was fully restored by the local community as a millennium project and unveiled in October 2000.
