St. Ann Lake is the only large volcanic lake in Europe that is sitting on an intact crater. The area is a natural reservation. The lake and the Ciomatul Mountain are mentioned in documents as early as 1349. Twice a year, on Ann’s name day and on the Day of Our Lady, a service used to be held in the small chapel on the lake.
”Anna stayed at the lake. She built a small chapel and prayed to God there till the end of her life for having saved her and her companions from a shameful end. She was sainted in her lifetime, and the lake was named after her, while the small chapel is a site of pilgrimage today.”
