An island in the lagoon Costanziaca was very important, probably the district of Torcello. The name was given in honor of the emperor Constantine and was located between the islands of St. Ariano, S. Cristina. The history of its foundation is similar to that of the other islands of the lagoon, and too: he had to present himself as a great center with numerous monasteries and churches. Of course we know that there was at least a monastery that housed the nuns of St. Maffio that due to deterioration in the environment of the island were transferred to Murano. Activities and evidence of this community does not remain nothing but mud and water.
La Laguna handed down, as always, fantastic stories, legends and truths, which in the course of the centuries have become intertwined to the point of no longer distinguish truth from fantasy. The mysteries of San Francesco del Deserto (A legend is told that there is even kept the flayed skin of a brother on what would have drawn a map of the mythical Seven Cities of Cibola), the house of the window of the east, the treasures buried in the mud, the throne of Attila and many more. La Laguna hides, in reality, under its blanket of water more and more unhealthy, important traces of a past charming, heartfelt memories of centers and rich, proud of its many monuments and churches of their own, densely populated, which were in some cases the tombs of early Doges. A real treasure that deserves 
protective action and research that enhances and highlights the public, turning the lagoon into an archaeological park of global significance, the splendor of a story now entrusted only to underwater archeology. The lagoon area where there were more findings of exhibits is that of the north lagoon, an area that over the centuries has undergone vast range of natural upheavals. The most important archaeological sites are known and the channel Treporti, the natural channel from the port of St. Nicholas goes to the channel of Burano, the channel S. Felix, from a depth of just over 4 meters returned amphorae and brick from the Romanesque period, and in which there are the remains of a Roman watchtower (a mighty structure of over 80 sqm.) Testifying as there existed a 'island. The origins of this treasure, Roman and post Roman, are known. The Lombard hordes UNNI and descending along the plain between the Piave and Sile, forced the former inhabitants of 'Altino to move to safer islands in the lagoon, soon imitated by the inhabitants of Opitergium (now Oderzo). So it was that well before the year one thousand, there was a myriad of islands and islets in the lagoon were inhabited by refugees eager to rebuild their city now lost and to create stable settlements. Many of them remains today only a few miserable rest, the memory of a name or, sometimes, no trace: Eraclea, Ammiana, Ammianella.La Care, Torcello, Malamocco (not the present but destroyed the ancient created by a tsunami that, in fact, Laguna), Costanziaca. The latter, the most mysterious and legendary object of a thousand speculations and assumptions, including the last mention goes back to a draft drawn maps 
by Piva for the study of the origins of the Patriarchate of Venice, could be defined more all the others and with good merit, city. It was inhabited by a considerable community, represented by fugitives d'Altino: spread over four islands linked by bridges, magnificent churches had at least six (dated prior to the seventh century) and was divided by a branch of Sile, which formed the main channel (now Care of the channel) in two parrocchie.Dove today there are salt marshes to the east of Torcello stood the church of S. Massimo and S. Marcellino, the monastery of St. Maur, the abbey of SS. Giovanni e Paolo. Where there is now the Isle of Care (which had not yet emerged) there were the churches of SS. Sergius and Bacchus and that of St. Matthew, all subject to the authority of Ammiana. The most famous island that make up Costanziaca has been identified (but that is all to be revised because it was probably only a fragment of the original island) with that of S. Arian (sometimes S. Adriano), which takes its name from the church steeple by the very visible from the lagoon, which tracks certain until the year 1490, after which it was turned into a charnel house by order of the Doges who did gird the island with a high wall, and housed a convent of Benedictine nuns founded in 1106 by the daughter of a noble woman Michiel Doge Vitale, and Giustiniani wife of Nicholas, who, before being confined in the convent had given her peace with her husband many as 13 children. The convent, at the time, was attended by the best Venetian nobility, and the same have been recently excavated foundations. According to the mapping Piva (1927) in the Costanziaca would 
relapse even the basilica of St. Marcellin and St. Maximus, erected in 630 by the Bishop of Torcello Giuliano, originally assigned to the artistic heritage of Ammiana. In any case Costanziaca Ammiana was adjacent to the island famous Laguna Superior, which already had 15 in 600 churches and monasteries, including the basilica of St. Peter Casacalba which stood where now stands the motto of Cunicci (one of the few remains so far surfaced after several sinkholes that places have undergone over the centuries, it is believed due to two successive tidal waves). The mutant sea currents, the land became unhealthy dall'impaludamento the surrounding lagoon, which already caused the beginning of 1400 the islands were virtually abandoned. Unique and last bastion of humanity was represented by S. Ariano monastery, which he had to suffer such invasions of serpents and snakes to force the nuns (in 1349) to leave and find shelter in Torcello, and then, by decree of Pope Paul III, moved to the Monastery of St. Angelo, Zampenigo to Torcello and then the Convent of St. Jerome, which was attributed to all the property in the area of \u200b\u200bS. Ariano. It is said in the winter evenings in Portegrandi, including a "separation" and a shadow, that amateur archaeologists flying, secretly, the lagoon to escape the discreet surveillance of the authorities, have found amphorae, coins, remains of boats , jewelry, before and after Christ, and even that has been identified that could be paving the main street of any city, almost certainly from Roman times, mired in mud. What is certain is that the Romans well knew and practiced area: here is the way Annia, also known as Emilia Altinate, which connected to Aquileia through Altinum Adria. So do not be shocked if it is descriptive treats that can be hidden under the sandbanks an entire city. In these places submerged and partially submerged the islands have been known for centuries, and traces of ancient Palafiere

Costanziaca the legendary and mysterious, with its town and district Costanziaca Costanziaca Major Minor, was to be built here, including the ossuary and the island of St. Christina S. Ariano, in what is now known as the Swamp of Centrega . What is certain saltmarsh is that sometimes returns a few small remnant of a tile mosaic ... maybe, maybe ... sometimes a coin jar. The lagoon helps to build, but can also destroy the lagoon. I passed the old memories WATER Great, who must be identified by the two great historical tsunamis that have hit the Laguna area today, sweeping the islands and people, and making new landscapes emerge on which to build the history of Venice. Whispers in the lagoon? Fantastic legends? Imagination of sailors use to enjoy a good bacaro? No, the historical truth! Not yet fully established only because the firm would be colossal. Formulated a hypothesis for some time, it would be part of the Cordon lagoon or salt marsh, drained by the waters, and start to dig, but basically, it would cost a fortune to reveal what we already know, perhaps by adding a bit 'of romantic imagination that adorned the knowledge tested. Better to let him sleep in peace to our island is not there, and let all of us can fantasize about where it is actually buried in the mud of the salt marsh, with its majestic churches, its towers, Roman villas and monasteries. Let her sleep in peace, let us commend his memory to the whispers of the lagoon, a perennial pride in our history, both large and, unfortunately, sometimes, so little known.
