From Catholic Herald:
The convent’s very existence fulfils the prophecy made in 1585 by Fr Gregory Gunne when, during his own trial, he rebuked an Elizabethan court for having sentenced St Edmund Campion to death at Tyburn. “You have slain the greatest man in England,” he said. “I will add that one day there, where you have put him to death, a religious house will arise, thanks to an important offering.”
We can't discover the outcome of Gunne's trial - was he also put to death at Tyburn?
