An Instagram reel using 3D animation argues that Venice was built by driving thousands of wooden piles into the lagoon floor, topped with wooden platforms and stone, and that the submerged timber has survived for centuries because oxygen-poor water prevents wood-decaying organisms.
Evidence indicates both claims are likely true in their essentials: Venice's foundations do rest on dense fields of wooden piles topped by wooden platforms and stone, and anoxic submersion is the standard explanation for the timber's survival. However, the reel simplifies the engineering (piles work largely by friction and sediment compaction rather than bearing on hard 'stable layers') and overstates preservation (anaerobic bacteria still slowly degrade the wood). Because automated research retrieved no external sources, this verdict rests on domain consensus and carries low confidence.
