Arc de Triomphe is located on the right bank of the Seine at the centre of a dodecagonal configuration of twelve radiating avenues. It was commissioned in 1806 after the victory of Austerlitz by Emporer Napoleon at the peak of his fortunes. Laying the foundation alone took two years, and in 1810, when Napoleon entered Paris from the west with his bride Arcduchess Marie-Louise of Austria, he had a wooden mock-up of the completed arch constructed.
