What happened
In 1411 at Ludbreg, a priest doubting the Real Presence saw, at the consecration, the wine in the chalice turn to visible blood. In fear, he sealed it into the wall of the chapel.
Generations later, after reports of graces, Pope Leo X examined the case and, by a bull of 1513, permitted public veneration of the relic. Ludbreg still keeps its "Holy Sunday" each year.
Where it stands
Public veneration permitted by a bull of Pope Leo X (1513); kept yearly as "Holy Sunday" (Sveta Nedilja).
Church recognition is a judgment about devotion — not a claim of scientific proof. We keep the two distinct.

The bigger picture
This case is one witness in a much longer story — the Catholic teaching that Christ is truly, substantially present in the Eucharist.
