A church at the site of current San Francesco, dedicated to St John, was present since perhaps the seventh-century, since nearby Christian burial appear to date from then. In around 1244, the church began to be administered by priests from the Cathedral of Acqui. Around 1410, it became associated with the Franciscan order, and rebuilt and rededicated. The convent was suppressed in 1802, and the church was affiliated with the Confraternity of San Giuseppe, who briefly changed the name of the church. In 1824, the Franciscans returned, and they rebuilt the church in a neoclassic-style, adding the Facade, under the design of Ferraris in 1835, completed in 1854.
Parts of the church are ancient. The bell-tower and apse date to the 15th century. But other parts reflect refurbishments along the centuries, including the 19th-century reconstruction. The broad brick facade (1835–1854) shows eclectic styles with a triangular lower tympanum and monumental order pilasters.
The interior houses an Immaculate Conception by il Moncalvo; an Adoration of the Magi by Raffael Angelo Soleri; and a Madonna and Child with Saint Francis and Antony of Padua by Pietro Beccaria. The ceilings were frescoed by the 19th-century painter Pietro Ivaldi, detto il Muto di Toleto.References:
Prunn Castle is perched on an almost vertical Jurassic outcrop high above the Altmühl river valley south-west of Regensburg. Its impressive appearance from a distance is matched by the views from the castle of the surrounding Altmühltal countryside.
Lords of Prunn were first mentioned in 1037, and they will have certainly chosen the site because of its favourable position on several transportation routes. The castle itself dates from around 1200, a time when many castles were being built. The Danube region centring around Kelheim became very important in this period under the Bavarian duke Ludwig I. One of the oldest parts of the castle is the 31-metre keep.
In 1288, Duke Ludwig of Bavaria acquired the castle from the lords of Prunn-Laaber. In the first half of the 14th century the duke then invested the Fraunberg vom Haag family with the castle.
