Piona Abbey is a religious complex on the bank of Lake Como. The abbey is set at the top of a small peninsula, the Olgiasca, which points into the lake, creating an inlet.
The original church of Saint Justina was founded in the 7th century; the ruins of an apse behind the current church of San Nicola belong to this original edifice. A new church was added some centuries later, though before 1138, as testified by an inscription reporting its reconsecration in that date. which was followed - some centuries afterwards - by a priory, with its monastery complex, part of the political-religious network which was led by Cluny and its reform movement.
The location, although away from the main town, was on a military route of critical importance in the wars of the times.
The abbey was built in Lombard Gothic style, with French influences. The church has a single nave, and the edifice dates mostly from the 12th century reconstruction. The bell tower dates from the 18th century. A previous one, with an octagonal plan, was located on the other side of the church.
The apse has internally some depleted frescoes, dating from the 12th-13th centuries, with Apostles of Byzantine style. The cloister has an irregularly quadrangular plan, and has round arches supported by columns with different type capitals. The northern wall of the portico has a fresco with a symbolic calendar, depicting the months and the different works associated to them.
References:The Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
