A small monastery was founded in Altomünster by Saint Alto, a wandering monk, in about 750. The vita of Alto, likely written by Otloh of St. Emmeram after 1056 and ostensibly based on oral knowledge (written lore having been lost through plunder), reports that the monastery was visited by Saint Boniface, who dedicated the church. Another 11th-century text notes that Boniface also dedicated the church in nearby Benediktbeuern Abbey.
Sometime before 1000 the Welfs enlarged it and made it into a Benedictine abbey. Welf I, Duke of Bavaria resettled the monks in 1056 to the newly founded Weingarten Abbey in Altdorf, while the nuns formerly resident at Altdorf moved to Altomünster, where they lived until the monastery was dissolved in 1488 by Pope Innocent VIII.
In 1496 by grant of Duke George the Rich the Bridgettines of Maihingen were permitted to establish a Bridgettine monastery at Altomünster. The monastery was dissolved on 18 March 1803 during the secularisation of Bavaria, but was later revived. Today, along with a settlement in Bremen, it is the last Bridgettine monastery in Germany. Nearby is a museum of the history of the Bridgettine Order.
Two gospel lectionary created for the abbey in the 12th century are held by the Bavarian State Library.
References:The Temple of Edfu is one of the best preserved ancient shrines in Egypt. It was built in the Ptolemaic Kingdom between 237 and 57 BC.
Edfu was one of several temples built during the Ptolemaic Kingdom, including the Dendera Temple complex, Esna, the Temple of Kom Ombo, and Philae. Its size reflects the relative prosperity of the time. The present temple initially consisted of a pillared hall, two transverse halls, and a barque sanctuary surrounded by chapels. The building was started during the reign of Ptolemy III Euergetes and completed in 57 BC under Ptolemy XII Auletes. It was built on the site of an earlier, smaller temple also dedicated to Horus, although the previous structure was oriented east–west rather than north–south as in the present site.
