The Saint Petersburg Botanical Garden, also known as the Botanic Gardens of the Komarov Botanical Institute, is the oldest botanical garden in Russia. It consists of outdoor and indoor collections situated on Aptekarsky Island in Saint Petersburg and belongs to the Komarov Botanical Institute of the Russian Academy of Sciences.
The garden was founded by Peter the Great in 1714 as a herb garden in order to grow medicinal plants and re-established as a botanical institution under the name Imperial Botanical Garden in 1823. Ivan Lepyokhin was in charge of the botanical garden from 1774 until 1802. Beginning in 1855, Eduard August von Regel was associated with the garden, first as Scientific Director and then as Director General (1875-1892). Regel had a particular fascination with the genus Allium, overseeing collections of these plants in the Russian Far East and writing about them in two monographs. More than 60 of the alliums he identified bear his name, e.g., A. giganteum Regel and A. rosenbahianum Regel. Many alliums can be viewed in the Northern Yard of the garden.
In 1930 the garden became subordinate to the Academy of Sciences of the Soviet Union and in 1931 was merged with the Botanical Museum into the Botanical Institute.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.
