In the early twentieth century, before the Second World War, there was a memorial, near the alms houses in Llanfaes. It has since disappeared. An early photograph is shown here.
The middle section lists those who died and the outer sections, the other Brecon men who served in the war.
Now in the church, there is a large wooden board in the ringing room, containing a roll of honour of all who served as well as those who died. Names are also inscribed on a wood panel at the entrance of ringing room. A tablet recording a roll of honour is near up the altar and pulpit.
