St. Peter's Abbey on the Madron was a Benedictine monastery in Flintsbach. The church, now a pilgrimage church known as the Peterskirchlein, still stands on the site.
The Madron is a mountain known also as the Petersberg. It was occupied in ancient times, showing traces of Bronze Age settlement.
A poorly documented monastic foundation dating from sometime in the 8th century and settled by monks from St. Peter's Abbey in Salzburg was destroyed by the Hungarian invasion of the early 10th century. A supposed resettlement in about 955 by refugee monks from Wessobrunn Abbey is equally poorly evidenced.
In 1130 however the monastery, dedicated to Saint Peter, was definitely (re)founded by Count Siboto of Falkenstein and resettled by monks from Weihenstephan Abbey in Freising. The Counts of Falkenstein-Neuburg were also the abbey's Vögte (lords protector) and endowed it with a number of estates. They gave the abbey to the Bishop of Freising in 1163, but retained the office of Vogt. The monastery was destroyed in 1296 during a dynastic conflict, and never rebuilt. The site became from the 14th century a prebend for a canon of Freising Cathedral, part of whose responsibilities was to oversee the long-established pilgrimage here. It was dissolved in the secularisation of 1803.
The area for which the place had pastoral responsibility was extremely small, but against expectation, the church survived and became shortly afterward the centre of a renewed interest in the tradition of the pilgrimage. The church is today a well-known landmark on its mountain.References:
Monte d"Accoddi is a Neolithic archaeological site in northern Sardinia, located in the territory of Sassari. The site consists of a massive raised stone platform thought to have been an altar. It was constructed by the Ozieri culture or earlier, with the oldest parts dated to around 4,000–3,650 BC.
The site was discovered in 1954 in a field owned by the Segni family. No chambers or entrances to the mound have been found, leading to the presumption it was an altar, a temple or a step pyramid. It may have also served an observational function, as its square plan is coordinated with the cardinal points of the compass.
The initial Ozieri structure was abandoned or destroyed around 3000 BC, with traces of fire found in the archeological evidence. Around 2800 BC the remains of the original structure were completely covered with a layered mixture of earth and stone, and large blocks of limestone were then applied to establish a second platform, truncated by a step pyramid (36 m × 29 m, about 10 m in height), accessible by means of a second ramp, 42 m long, built over the older one. This second temple resembles contemporary Mesopotamian ziggurats, and is attributed to the Abealzu-Filigosa culture.
Archeological excavations from the chalcolithic Abealzu-Filigosa layers indicate the Monte d"Accoddi was used for animal sacrifice, with the remains of sheep, cattle, and swine recovered in near equal proportions. It is among the earliest known sacrificial sites in Western Europe.
The site appears to have been abandoned again around 1800 BC, at the onset of the Nuragic age.
The monument was partially reconstructed during the 1980s. It is open to the public and accessible by the old route of SS131 highway, near the hamlet of Ottava. It is 14,9 km from Sassari and 45 km from Alghero. There is no public transportation to the site. The opening times vary throughout the year.
