St Tekla is a rather enigmatic saint - there doesn't even seem to be much agreement about the spelling of her name and at least two other places claim to be her last resting place. Anyway, according to legend she was an early convert to christianity and a follower of St Paul who broke off her engagement to devote herself to god. Her vengeful fiance tried to kill her by various means, all of which were thwarted by divine intervention. Eventually she is supposed to have hidden away in a grotto in the cliff around which the modern convent was built.
