The Ossario di San Martino is a small chapel that houses over 1,200 skulls and over 2,000 bones that belonged to fallen soldiers who fought in a key 19th-century European conflict.
In 1859, during the Second Italian War of Independence, there was a great battle here, more commonly called the Battle of Solferino. It was fought out between Austrian and the Piedmontese army. Solferino was the largest battle since that at Leipzig in 1813. As a result of their defeat, the Austrians lost their grip on the region.
Originally built as a chapel, the Ossario di San Martino was later converted into an ossuary, which was opened in 1870. Thousands of bones and skulls from soldiers from both sides, exhumed from the mass graves in which they were buried, rest in a display behind the altar. The exterior walls contain plaques commemorating the fighters from different cities and regions who took part in the war.
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.
