Rhydcymerau is the birthplace of prominent Welsh writer and nationalist David John Williams, one of three saboteurs of the Penyberth bombing school in 1936. Two of his autobiographical volumes, Hen Dŷ Ffarm (“The Old Farmhouse”, 1953) and Yn Chwech ar Hugain Oed (“Twenty-Six Years Old”, 1959) give a portrait of life in this small town at the turn of the twentieth century.
The Red Dragon pub, which had been closed for several years, was partly demolished in 2016 despite a planning application to do so not having been considered.
