a circular geometric garden with an axis perpendicular to the water reservoir. The style of the Rotonda Garden is a mixture of Liberty and Classicism but it also presents features of the 20th century. The architectural style recalls the late baroque, but it is also rich in classical references, for example the flower urns and the tower mausoleum are carried out with a secessionist taste, while the shape of the flower beds, (round elliptic and drop-like), are typically liberty. In the flower beds are low bushes that are reminiscent of palms and agaves. At first the garden was apparently meant to hold few shrubby plants to be exposed to the light so as to put the main elements in contact with the water of the garden. At present the garden is being neglected and the trees that live here have no intrinsic value. These trees represent a serious problem for the masonry banks because their roots push on them. The main entrance is characterized by an imposing wrought-iron railing in liberty style. The garden has and overturned- L-shape which proceeds long and narrow in the balcony and terraces and widens at the end of these, where the water reservoir is situated. On it there are geometric elements in the lower part, floral decorations in the central park and Padua coat of arms in the upper part. At the bottom of the garden there is the stately water reservoir; its main fountain, which has a temple form, is close to a strong terraced wall structure. Inside there are some circular pilasters connected to each other by means of perimeterl and radial concrete arches, disposed on two overlapping floors because they have to support the suspended water reservoir properly. The story of the aqueduct started on 26 August 1875, when the Mayor said “water is so vital to man and society, like air and light, that an abundance of water distribution and a regular distribution to the whole city, deserve to be fully kept alive in the citizens’ memories”. Following study, water from the Brenta and Bacchiglione rivers was excluded owing to their torpidity and bacterial counts, instead water of Dueville source was chosen. On 17 February 1886, the Padua town hall granted the management of the new aqueduct to Società Veneta per Imprese and Costruzioni Pubbliche. On 13 1888 in Unità d’ Italia Square, the much expected event took place: in
