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:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
