<div>The '''St. Mark's Square archaeological digs''' refer to a series of excavations conducted in Piazza San Marco in Venice, Italy, primarily between 2023 and 2024. Taking advantage of a municipal project to restore the square's traditional paving stones (''masegni''), archaeologists uncovered nearly a thousand years of history compressed into just 50 to 60 centimeters of stratigraphy. Significant discoveries include the remains of the lost medieval church of San Geminiano, historic market structures, and medieval burials.</div>
<div><br></div>
<div>== Background and Excavation ==</div>
<div>Due to the delicate nature of the Venetian lagoon—characterized by subsidence, changing sea levels, and constant urban rebuilding—archaeology in Venice is highly unique. The excavations were directed by Dr. Sara Bini of the Superintendence of Archaeology, Fine Arts, and Landscape for the Municipality of Venice and the Lagoon, and carried out by the archaeological firm Semper s.r.l.</div>
<div><br></div>
<div>The project was initiated in conjunction with the municipality of Venice's restoration of the square's paving stones. Working in difficult conditions involving mud and seawater just below the surface, the team utilized advanced excavation methodologies to expand upon late 19th-century surveys conducted by Federico Berchet and Giacomo Boni between 1885 and 1889.</div>
<div><br></div>
<div>== Key Discoveries ==</div>
<div><br></div>
<div>=== The Lost Church of San Geminiano ===</div>
<div>Underneath the Procuratie Vecchie, archaeologists discovered a series of walls and floor levels identified as belonging to the ancient medieval church of San Geminiano. Historically, this church predated the current monumental shape of the square. It was eventually demolished by the doges to expand the square in front of St Mark's Basilica, and a later iteration of the church was destroyed by Napoleon.</div>
<div><br></div>
<div>=== Medieval Burials ===</div>
<div>Surrounding and inside the structural remains of San Geminiano, archaeologists excavated several medieval tombs. Notably, one brick-lined burial contained the remains of at least four individuals. Some of these tombs were constructed using Roman spoliated material, likely brought from the nearby ancient city of Altino. The human remains offer crucial anthropological data regarding the diet, diseases, gender, and social status of early Venetians.</div>
<div><br></div>
<div>=== Market Structures and Artifacts ===</div>
<div>Near Caffè Quadri, investigations revealed brick plinths that once supported Renaissance-era market stalls. These are the same vibrant market stalls visible in the 18th-century paintings of Venetian ''vedutisti'' such as Canaletto. Associated artifacts found in this layer include a historical balance weight and a heavily worn marketplace coin, representing the first coin to emerge from excavations in the square in recent years.</div>

:This page is an overview of all the wells on Venice. For a typical well, see Well.
Wells were the primary drinking sources in Venice between the 11th century and the 19th century. There are more than 5,000 cistern wells under the streets of Venice, but their wellheads have almost all been removed or destroyed, leaving only 260 remaining wellheads in the city. These wells no longer serve any functional purpose but still exist beneath the streets.
As a collection of islands surrounded by a salt-water lagoon, Venice lacks natural sources of freshwater. As a result, Venice had to find alternative ways to obtain freshwater for the city. Before the introduction of the cistern system, the citizens of Venice relied on a few different sources of freshwater. They caught rain in basins, ran barges to the mainland to collect water from groundwells, and dug shallow wells in the Lido to reach pockets of drinking water. These pockets were the result of rainwater filtering through the fine sands of the Lido beaches. Although these sources brought freshwater, they came with many drawbacks. This system mainly relied on the barges to supply water to the city, which was very expensive in both manpower and resources.
=== The Cistern System ===
The oldest known Venetian cistern-wells were constructed in the eleventh century, around 1038 [1], and were spread out across the Venetian landscape. The construction of the cistern system allowed the people of Venice to gather water without needing the barges to transport it from the mainland [2]. These "wells" were actually cisterns that emulated the natural filtration of the Lido's sand dunes. They collected rainwater through street-level drains, filtered it through layers of sand from the Lido, and held the drinkable water to be collected for later use. This system was implemented slowly throughout Venice for the next two hundred years. Then, in the 13th-15th centuries, the city built wells in every campo and corte to make clean water as accessible as possible. Once the wells became commonplace, Venice's reliance on the water-carrying barges reduced greatly. The barges were not fully eliminated, however, since they were in charge of filling the wells with water from the mainland when the wells began to run dry.
The water in the public cisterns was free for anyone to use, and proximity to water was a great signifier of power in Venetian society. Wealthy citizens would commission guilds to build private wells to separate themselves from the rest of the population or to display their opulence. There were also many private wellheads located in religious buildings. Priests and other leaders closely and strictly supervised the use of wellheads, allowing limited accessibility to the wells a couple of times per day [3].
Several guilds were in charge of building and maintaining the wells. The guild of the burchieri used barges to transport materials to the islands of Venice. The two notable sub-divisions (colonnelli in Italian) of the burchieri were the burchieri-acquaroli and the burchieri da fango. The burchieri-acquaroli brought water from the mainlands when the wells began running low. The burchieri da fango were in charge of bringing sand from the Lido to the islands to use in the wellhead's filtration system. The pozzeri and mureri were in charge of building and repairing the cisterns and wellshafts. When well water was contaminated, there was a guild to pump the dirty water out and another guild to clean the wellshaft before the acquaroli refilled the wells.
While the cisterns were vital to the survival of Venice, they did not come without their drawbacks. Their construction was very difficult, requiring the use of multiple different trades, and there was a risk of contamination to the well water. In 1575, there was an epidemic that took out nearly a third of Venice's population [4]. Earlier that year, an unusually high flood let saltwater seep into the wells' drains and some wells' lids. The saltwater and freshwater mixed to create “a certain muddy mixture so foul that it caused illness” [5]. Despite efforts to clean out the wells, some of the saltwater remained and mixed with the new freshwater as it came in, drawing out the epidemic. After 15 months of consuming the contaminated water, the sickness worsened. Although the public health officials were fast in their action, the city's doctors ignored the symptoms and neglected poor patients [6]. The neglect allowed this illness to turn into the worst epidemic in Venetian history. This epidemic left Venice with a heavy focus on finding a better water source than the cisterns in order to avoid an incident like this happening again.
This was Venice's system for fresh water supply until 1884, when the Venetian aqueduct was constructed, providing Venice with a more reliable and safer source of drinking water [7].
== Function ==
A design of a Venetian well system. (Rizzi, 1981)
A typical Venetian well has a clay basin that stores rainwater underground and a wellhead to retrieve the water from above ground. Rainwater collects through street-level drains, filters through fine river sand, and then accumulates at the bottom of the basin. The water is filtered again as it travels through the brick lining the well shaft. Then, citizens could retrieve water through the street-level wellhead.
The locations of the currently known wellheads are designated by red dots on the map. There are more wells buried under the streets of Venice, but we do not currently know where they are.
