The Andrew Carnegie Mansion is a historic house located at 2 East 91st Street at Fifth Avenue in the Upper East Side of Manhattan. Andrew Carnegie moved into his newly completed mansion in late 1902 and lived there until his death in 1919; his wife, Louise, continued to live there until her death in 1946. The building is now the Cooper-Hewitt, Smithsonian Design Museum, part of the Smithsonian Institution. The surrounding area, part of the larger Upper East Side neighborhood, has come to be called Carnegie Hill. The mansion was named a National Historic Landmark in 1966.
The house is a 3+1⁄2-story structure, finished in brick and stone. It is stylistically an eclectic variation of the Georgian Revival, with stone ashlar corner quoining, windows with heavy stone trim, and a dentillated cornice topped by an urned balustrade. A grassy lawn separates the house from 91st Street, and there is a small garden on its west side. Just east of the mansion proper is a townhouse that was purchased by Carnegie soon after its 1905 construction as a residence for his daughter. This building forms part of the current complex, although its interior has been modernized and converted to office and administrative uses by the Smithsonian.
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.
