Overview: Giovanni Boccaccio, the Italian writer of the century. XIV, produced his masterpiece, Decameron, in the aftermath of the Black Death that devastated a third of the European population. The black environment of those times of plague, so well described in Decameron, explains, in part, the type of architecture that was produced in that period. In Terena, in the Alentejo region, a small church-fortress from the 19th century. XIV still stands as a singular (and perfect) witness to a time of frenzy, distrust and fear. But the Church of Boa Nova de Terena also tells many other stories, some of them mysterious. A guided tour by art historian José Custódio Vieira da Silva.
