In my second novel, Eleri’s Tale, my character Eleri spends time at “Candida Casa”, the “white house” on the hill at the very southwestern tip of Scotland.
The time period is 432 AD. Candida Casa was a monastery built by St. Ninian. St. Ninian’s Cave is on the beach at the Irish Sea, a walk of about 4 miles. Tradition holds that Ninian retired to this cave to pray and meditate.
