The promontory itself consisted of two parts - the hill of Munychia, and the projection of Acte; on the opposite side of the great harbour was the outwork of Eetioneia.
Thick, was found in 1886 running diagonally across the new cemetery, and in 1903 an outwork in front of it was discovered (P. Orsi, in Notizie degli scavi, 1903, 517).
The Babil mound probably represents the site of a palace built by Nebuchadrezzar at the northern extremity of the city walls and attached to a defensive outwork 60 cubits in length.
By a fortunate accident the isolated outwork was just missed in the darkness by the left flank of the 2nd Division; otherwise a premature alarm would have been given, which must have changed all the conditions of the operation.
Wrought into a deep, hollow cup, plastered with earth, and lined with fibres; but around this is erected a firmly interwoven, basket-like outwork of thorny sticks, forming a dome over the nest, and leaving but a single hole in the side for entrance and exit, so that the whole structure is rendered almost impregnable.
During the popular movements of 1831 Marie Louise had to take refuge with the Austrian garrison at Piacenza; on the restoration of her rule by the Austrians its character deteriorated, Parma becoming an outwork of the Austrian empire.
This succeeded beyond Vauban's own expectation; the picked troops entrusted with the attack of an outwork forced their way into the town itself (March 17th).
