Venetian Lagoon
enclosed bay of the Adriatic Sea
The Venetian Lagoon, also Venice Lagoon or Lagoon of Venice, is an enclosed bay of the Adriatic Sea, in northern Italy, in which the city of Venice is situated. Its name, from a Venetian derivative of Latin lacus 'lake', has become the generalized English term for any enclosed, shallow embayment of salt water – a lagoon.
Location
The Venetian Lagoon stretches from the River Sile in the north to the Brenta in the south, with a surface area of around 550 square kilometres (212 square miles). It is around 8% land, including Venice itself and many smaller islands. About 11% is permanently covered by open water, or canals, as the network of dredged channels are called, while around 80% consists of mud flats, tidal shallows and salt marshes. The Lagoon is the largest wetland in the Mediterranean Basin.
It is connected to the Adriatic Sea by three inlets: Lido, Malamocco and Chioggia. Situated at one end of a largely enclosed sea, the lagoon is subject to large variations in its water level. The most extreme are the spring tides known as the acqua alta (Italian for "high water"), which regularly flood much of Venice.
The nearby Marano-Grado Lagoon, with a surface area of around 160 square kilometres (62 square miles), is the northernmost lagoon in the Adriatic Sea and is sometimes called the "twin sister of the Venice lagoon".
Begin with the source’s own compact description: “Venetian Lagoon” is enclosed bay of the Adriatic Sea. The dossier treats that line as a proposition to test through Venetian, Lagoon and enclosed, not as a finished interpretation.
Why this record matters
The phrase “enclosed bay of the Adriatic Sea” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
The strongest evidence will usually combine a dated visual record with documents produced by the authority responsible for the place. The source revision retrieved here is dated Sep 24, 2026. The linked authority identifier is Q76925. VIAF identifies the subject as 173091625. The Library of Congress control number is sh85142737. Authority coordinates are 45.413, 12.297. 2 of 3 selected statements include explicit references; 1 carry qualifiers and 0 use preferred rank.
Modern boundaries and familiar names can conceal earlier jurisdictions or structures that do not align with the present site. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
