The Celts had a unique way of looking at water and wells. Water was the boundary between the otherworld and our world. It was the boundary between land and sky, similar in nature to the special time of dawn and dusk, noon and midnight. It was between land and sky. Caves, caverns, wells and springs were all boundaries or gateways to the otherworld and were all places to communicate with deity. Since the water came from the otherworld and/or deep from the earth it was especially blessed.
