Where did Saint Christina of Bolsena live?

She died about the year 250 near Lake Bolsena, Tuscany, Italy.

Her father tied a rock around her neck, and threw her into Lake Bolsena.

When she miraculously survived, her tongue was cut out, and she was thrown into a furnace. When she again survived, she was shot full of arrows on the order of a magistrate persecuting Christians by order of Diocletian.
