	Mary Jones World () is a small heritage centre located in Llanycil near Bala, Gwynedd, Wales. Situated on the north shore of Bala Lake, it provides information on Mary Jones, a fifteen-year-old girl from Llanfihangel-y-Pennant. After she had saved her money for six years, in 1800 Jones walked 26 miles to buy a Welsh language Bible, which were very rare in those days.
