Eldena Abbey, originally Hilda Abbey, is a former Cistercian monastery. Only ruins survive, which are well known as a frequent subject of Caspar David Friedrich's paintings.
In the 12th century the Baltic coast south of the island of Rügen belonged to the Rani principality of Rügen, which in its turn was subject to the Danes. The Danish Cistercian monastery, Esrum Abbey, was thus able to found a daughter house in the area, Dargun Abbey, at Dargun, west of Demmin, in 1172. When in 1198 this monastery was destroyed in fighting between Denmark and Brandenburg, Jaromar I, Prince of the Rani, whose wife was of the Danish royal house, offered to re-settle the monks at a new site at the mouth of the River Ryck, close to the boundary between the territory of the Princes of Rügen, and the County of Gützkow, since the early 1120s subordinate to the Duchy of Pomerania.
The offer of the site, which included profitable salt-pans, was accepted, and in 1199 Hilda Abbey was founded and confirmed by Pope Innocent III in 1204. The monastery became wealthy from the salt trade and was very influential in the Christianisation of Western Pomerania. It also brought about the foundation at the beginning of the 13th century of the town of Greifswald, which started out as the monastery's trading settlement opposite the salt-pans, near the point where the via regia, an important trade route, crossed the river. After the Battle of Bornhöved in 1227 the Danes withdrew from this part of their former territories, and despite some competition from the princes of Rügen, the Duke of Pomerania, Wartislaw III, was able in 1248/49 to pressurise the abbey into subinfeudating Greifswald to him. Wartislaw was later buried in Eldena Abbey, as were later members of the ducal family, the House of Pomerania.
Throughout the 13th century, Eldena Abbey organized the cultivation and settlement of its growing estates in the Ostsiedlung process, allocating and founding Wendish, Danish and German villages. In the growing town of Greifswald however, the Cistercians of Eldena lost much of their influence the foundation in the town in the mid-13th century of friaries of the Franciscans (Greyfriars) and the Dominicans (Blackfriars).
The east end of the abbey church was built in about 1200, while the conventual buildings date from the mid-13th and 14th centuries, all in Brick Gothic. The final stages of construction were the west front and the nave of the church, which were completed in the 15th century.
The abbey was dissolved in 1535, when the Reformation was introduced into Pomerania by Duke Philip I, who took over its estates. The buildings were severely damaged during the Thirty Years' War. In 1634 the site was given to the University of Greifswald. The buildings fell into dereliction during the Swedish occupation of Western Pomerania (1648–1815) and the bricks were quarried for the building of fortifications.
By the beginning of the 19th century, when the Romantic painter Caspar David Friedrich knew the abbey, it was a ruin, which he made the subject of several paintings. Renewed public interest led to the beginning of restoration work in 1828, and on the basis of designs by the Prussian landscape gardener Peter Joseph Lenné a park was laid out on the abbey precinct.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.
