In 376, the Ostrogoths, fleeing from the Huns, received permission from Emperor Valens (r. 364378) to settle in the Roman province of Thracia in the Balkans. The settlement did not go smoothly, and when Roman officials mishandled the situation, the Ostrogoths began to raid and plunder.[D] Valens, attempting to put down the disorder, was killed fighting the Ostrogoths at the Battle of Adrianople on 9 August 378. As well as the threat from such tribal confederacies from the north, internal divisions within the empire, especially within the Christian Church, caused problems. In 400, the Visigoths invaded the Western Roman Empire and, although briefly forced back from Italy, in 410 sacked the city of Rome. In 406 the Alans, Vandals, and Suevi crossed into Gaul; over the next three years they spread across Gaul and in 409 crossed the Pyrenees Mountains into modern-day Spain. The Migration Period began, where various people, initially largely Germanic peoples, moved across Europe. The Franks, Alemanni, and the Burgundians all ended up in northern Gaul while the Angles, Saxons, and Jutes settled in Britain. In the 430s the Huns began invading the empire; their king Attila (r. 434453) led invasions into the Balkans in 442 and 447, Gaul in 451, and Italy in 452. The Hunnic threat remained until Attila's death in 453, when the Hunnic confederation he led fell apart. These invasions by the tribes completely changed the political and demographic nature of what had been the Western Roman Empire.

Ah, so.. 9 August 378

In Britain a number of architects are active in the neoclassical style. Two new university Libraries, Quinlan Terry's Maitland Robinson Library at Downing College and ADAM Architecture's Sackler Library illustrate that the approach taken can range from the traditional, in the former case, to the unconventional, in the latter case. Recently, Prince Charles came under controversy for promoting a classically designed development on the land of the former Chelsea Barracks in London. Writing to the Qatari Royal family (who were funding the development through the property development company Qatari Diar) he condemned the accepted modernist plans, instead advocating a classical approach. His appeal was met with success and the plans were withdrawn. A new design by architecture house Dixon Jones is currently being drafted.

Ah, so.. Prince Charles

Standing at 117 metres (384 feet) in height and 360 metres (1,180 feet) in width, the Potala Palace is the most important example of Tibetan architecture. Formerly the residence of the Dalai Lama, it contains over one thousand rooms within thirteen stories, and houses portraits of the past Dalai Lamas and statues of the Buddha. It is divided between the outer White Palace, which serves as the administrative quarters, and the inner Red Quarters, which houses the assembly hall of the Lamas, chapels, 10,000 shrines, and a vast library of Buddhist scriptures. The Potala Palace is a World Heritage Site, as is Norbulingka, the former summer residence of the Dalai Lama.
