Llangasty which sits on the lake shores of Llangorse Lake at the foothills of The Black Mountains in Wales, is an ancient Celtic place of worship. St Gastyn, who discipled King Brychan's children lived here with his prayer oratory and Howell Harris, who is associated with the Methodist Welsh revival of the 18th century had a major encounter with the Holy Spirit here. An ancient well reopened and a portal still exists in this beautiful place of worship.
