The church of Portiuncula in Playa de Palma is really called Iglesia de Nuestra Señora de los Angeles de la Porciúncula. The temple is also known as Iglesia de Cristal (Glass Church).
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.
