From A Wiki of Ice and Fire
Jothiel's Pit is a fighting pit in Astapor.
A Storm of Swords
In Astapor, when Daenerys Targaryen is inspecting the Unsullied soldiers that she is considering purchasing, she remarks that whole men are stronger than eunuchs. Kraznys mo Nakloz replies that a bull is strong too, but bulls die every day in the fighting pits. He tells Dany that just three days ago a girl of nine killed one in Jothiel's Pit.
