Saint Gelert, also known as Celer, Celert or Kellarth (see below), was an early Celtic saint. Five locations in Wales are believed to bear his name: the Chapel of St Celer in Llandysul; Beddgelert ("Gelert's grave") and the surrounding Gelert Valley; Llangeler ("Gelert's church"); and the Church of St Celer in Llangeler.
