Capel Beulah is a Welsh black metal band which belongs to a group of bands that dub themselves "The Pembrokeshire Black Circle" along with Ogof, Plaguehurst, Revenant Marquis, and Crymych. Capel Beulah states this in an interview when asked about the origins of the bands name: "It is a chapel where I grew up where we would practice necromancy in our early teens. There is a stone within the grounds that has a potent, malignant energy that was used to in the recording of Black Cocoon".
