In the wake of tradition, the Monastery will host on May 18 a vocal concert. The group Ars Nova, under the musical direction of Prof. Alexandrino, will interpret church music of the 17th.-18th. centuries, mostly of Portuguese composers, some of them rarely given in concert. The concert is integrated in the Cultural Meeting organised by the Association of Friends of the Monastery, an annual event which will occur on May 18-19, for the eleventh time.
