 In 2014, residents of the village performed a musical piece to mark the centenary of the beginning of World War One.Entitled "WW1 – A Village Opera", the work, written by Pembrokeshire author and poet Peter George, with music by Llangwm resident Sam Howley, wove the stories of villagers affected by the war into the greater political narrative of the buildup to war.Llangwm is home to Pembrokeshire's newest literary festival, established by Michael Pugh.
