Venezia e la sua Laguna
Venezia (UNESCO 1987) è la città lagunare più studiata al mondo — costruita su 118 isolette unite da 400 ponti su 150 canali, fondata da profughi romani nell’Alto Medioevo, diventata la più potente repubblica mercantile del Mediterraneo (697–1797 CE), e oggi la più sfidante frontiera dell’adattamento climatico urbano con l’acqua alta che sommerge Piazza San Marco 100+ volte all’anno.

Venezia laguna (the most precisely Venezia zone Venezia Veneto Italy 45.4341 N 12.3388 E UNESCO WHS 1987 reference 394: the lagoon system (the Venetian lagoon (the Laguna Veneta): the largest coastal lagoon in the Mediterranean (550 km2 of total surface; 8% of the total Italian Adriatic coast; the lagoon has 3 inlets from the Adriatic Sea (the bocche di porto): Lido, Malamocco, Chioggia; the tidal range: approximately 1 m (the average spring tidal amplitude in the lagoon is 1.05 m; the range at Piazza San Marco is 0.8–1.2 m depending on meteorological conditions); the MOSE barrier (the Modulo Sperimentale Elettromeccanico: the flood barrier system completed 2020 CE: 78 mobile flap gates mounted on the lagoon floor at the 3 bocche di porto; each gate is a 30-tonne reinforced steel box (20 m × 4.5 m × 5 m) filled with water to remain on the floor; raised by compressed air injection when tidal levels >110 cm are forecast; cost: approximately €5.5 billion (the most expensive civil engineering project in Italian history))); the Basilica di San Marco (the Basilica of St Mark: the most important church in Venice and one of the most important in Europe: (1) the primary relic (the body of St Mark the Evangelist (c.1–74 CE): stolen from Alexandria, Egypt in 828 CE by Venetian merchants (Buono da Malamocco and Rustico da Torcello) who hid the body under layers of pork and cabbage to deter Muslim inspection at the Alexandria port); (2) the mosaics (the Byzantine golden mosaic programme: 8,000 m2 of gold-glass mosaic (the largest mosaic cycle in Western Christendom after the Hagia Sophia in Constantinople): the mosaic programme covers every surface of the 5-domed church (5 domes: one over the crossing, one over each of the 4 arms of the Greek cross plan; the total mosaic area of 8,000 m2 was created over 7 centuries (11th–17th century CE)); the specific mosaics (the Pala d’Oro (the “golden altar panel”; behind the high altar): the golden altarpiece of San Marco: 1.4 m × 3.45 m; 255 enameled panels set in gold; 1,300 pearls; 300 sapphires; 300 emeralds; 400 garnets; 90 amethysts; the most complex Byzantine enamel programme surviving outside Istanbul)); the Arsenal (the Arsenale di Venezia (founded 1104 CE; the gated shipyard complex in the eastern part of Venice; 32 hectares; the first example of industrial assembly-line production in history (the specific process: the Venetian war galley (the “galera sottile”: standard dimensions 39 m × 5 m × 1.5 m draft; 180 oarsmen; 30 soldiers; the building time (pre-Arsenal): 6 months; the building time (Arsenal assembly line): 1 day for finishing a hull pre-fabricated on a production line in which the hull moved along a canal past workshops that installed the rigging, oars, crossbows, and provisions at each station); the peak production rate (1570 CE: 100 galleys in 60 days for the Cyprus War (the Battle of Lepanto preparation); the rate confirmed by the Venetian chronicler Marino Sanudo)).
Key facts
- Il MOSE e la sfida dell’acqua alta — come funziona la barriera e quando viene attivata: the MOSE operation (the activation procedure: the Venice tide gauge (the “Centro Previsioni e Segnalazioni Maree” at Piazzale Roma): the forecast is issued 48 hours in advance for tides >80 cm; the activation decision is made 4–6 hours before the forecast high tide; the gates are raised in 30 minutes (compressed air is injected into each gate from the pier structure; the gate fills with air and pivots up; when all 78 gates are raised they form a continuous barrier across the 3 bocche di porto); the threshold (the current activation policy: gates raised when forecast >110 cm at Piazza San Marco; the “acqua alta eccezionale” threshold is >140 cm (the November 2019 flood reached 187 cm: the second-highest ever after the November 1966 flood of 194 cm)); the limitations (the MOSE cannot be activated for tides <110 cm (which still flood parts of Venice: Piazza San Marco floods at 80–90 cm); the barrier does not address the long-term subsidence of Venice (Venice has sunk 23 cm in the 20th century due to groundwater extraction stopped in 1975 CE); the combination of relative sea-level rise (the Adriatic is rising; Venice is sinking) means the MOSE threshold will need to be lowered over time))
