Master Manole was a famous architect commissioned by King Basarab I to build the most beautiful monastery in the country. However, the walls he built during the day would be destroyed at night. Manole had a dream that sacrificing his wife Ana would allow the monastery to be completed. Sadly, he fulfilled the prophecy, immuring her in the walls. When finished, all architects were sealed in the monastery's tower so they could not build elsewhere. Manole tried to escape by making wings but fell to his death.
