This simple small rural chapel at Rhosgwyn near Talgarth was built in 1862, probably designed by the most prolific Welsh chapels architect Thomas Thomas (research by John Pritchard from denominational sources). It is an attractive stone building in coursed rubble with two round-headed windows on the sides. It seated 60 people and was worth £150 at the time of the 1905 Royal Commission survey of Religious Buildings in Wales. It has now been converted into a house.
