The church and its monastic annex were built in 1964 and inaugurated in 1968. Originally, the complex was conceived as a seminary to prepare students for priesthood. Somehow, over the years, the Catholic church in Spain and in Mallorca has suffered a set-back, though, and monasteries, convents, monks, nuns and priests in general are now on the decline. I am not sure where the few candidates who nowadays elect clergy as a professional career are being taught; I suppose it might be at the Seminari Nou round the corner from Carrer de Monti-sion in Palma’s old town.
The Portiuncula church is of a circular shape; its main feature are the 39 stained glass windows designed by Juan Bautista Castro, a painter. The visual effects are quite stunning. You should go and have a look. There is also a Museo de la Porciúncula offering archeological titbits, ethnological oddities and a hodgepodge of numismatic items, recommended really only for its odd eccentricity. If you want to have a look at perhaps 300 maggot-eaten Cuban cigars, this is where you will find them, neatly arranged in glass display cases.
Occasionally, concerts are held here and not only of a religious content. The acoustic qualities of the church are quite remarkable. Again, if you would have the opportunity to attend, I feel you might not be disappointed.
