Bolsena, Province of Viterbo, Lazio Region, Italy
What to see:
Under the Romans Volsinii became an important centre strengthened along the Via Cassia. Bolsena is famous for a miracle in 1263, when a Bohemian priest doubting in the real presence of Christ's flesh and blood in the consecrated host, saw blood dropping from the host and staining the Mass linen cloth (=called corporal), which is now preserved in the Orvieto Cathedral. On that occasion the Corpus Domini festivity was established.
