Quarto d'Altino in the context of River Sile

The Sile (Venetian: Sil) is a 95 km river in the Veneto region in north-eastern Italy. Its springs are in the municipality of Vedelago in the Province of Treviso. It flows into the northern part of the Lagoon of Venice at the mouth of the River Piave Vecchia. It receives the waters of its tributary, the Botteniga, at Treviso.

Some of the rivers in the plain of the Veneto come from springs in the nearby Alps, while others have groundwater springs in the plain. The Sile originates in the plain and therefore it is a short river. Its springs are in the area of Albaredo, Casacorba and Cavasagra in the municipality of Vedelago. The fontanasso dea Coa Longa is considered to be the main spring. Two initial branches join at Morgano. The river has an initial west-east windy course which passes through or by Santa Cristina, Quinto di Treviso, Canizzano and Treviso. In Treviso it turns in a northwest-southeast direction towards the lagoon and passes by Silea, Casier, Cendon, Lughignano, Sant'Elena, Casale sul Sile, Quarto d'Altino, Trepalade and Portegrandi.

Roncade is a comune (municipality) in the Province of Treviso in the Italian region Veneto, located about 25 kilometres (16 mi) north of Venice and about 10 kilometres (6 mi) southeast of Treviso.

Roncade borders the following municipalities: Casale sul Sile, Meolo, Monastier di Treviso, Quarto d'Altino, San Biagio di Callalta, Silea.

Altinum (in Altino, a frazione of Quarto d'Altino) was an ancient town of the Veneti 15 km southeast of modern Treviso, close to the mainland shore of the Lagoon of Venice. It was also close to the mouths of the rivers Dese, Zero and Sile. A flourishing port and trading centre during the Roman period, it was destroyed by Attila the Hun in 452. The town recovered, but was later abandoned when sea-borne sand began to cover it over. Its inhabitants moved to Torcello and other islands of the northern part of the lagoon.

Today Altinum is an archaeological area and has a national archaeological museum.
