Ancient dovecote reused in modern times as a warehouse, province of Viterbo, central Italy. These particularly suggestive rooms are characterized by the presence of numerous small niches carved into the walls. The so-called columbaria were long thought to be Roman funerary monuments, but recently, thanks to the detailed descriptions of ancient scholars, the hypothesis has prevailed that they are environments excavated in the Middle Ages for the breeding of pigeons and doves.
