The Amphitheatre of Durrës was built in the beginning of the 2nd century AD. It was used for performances until the 4th century AD. The earthquake of 345/346 likely damaged the monument and closed it. An early Christian chapel was constructed on the amphitheatre in the second half of the 4th century. The chapel was initially decorated with frescoes; in the 6th century, mosaics were added. A medieval chapel was built in the 13th century, also decorated with frescoes. The amphitheatre was covered over in the 16th century, after the Ottoman occupation, when the wall was built nearby. In 2004 the University of Parma started restoration work to save the monument.
The amphitheatre has an elliptical shape with axes of 132 metres and 113 metres. It is built on a slope of the hill, and inside the amphitheatre there are staircases and galleries at different levels. The chapel with mosaics is preserved. The site currently functions as a museum.
It is the largest amphitheatre ever built in the Balkan Peninsula with once having a capacity of 20,000 people. The amphitheatre is included on the tentative list of Albania for inscribing it as a UNESCO World Heritage Site.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.
