Recent excavations in Cambridgeshire have unearthed two Roman wells dating back to the first century AD, revealing significant insights into Roman engineering practices. One well collapsed during construction due to inadequate wall support, while the second well, built 20 meters away, showcases improvements made by the builders, including wooden lining for stability. These finds highlight the trial-and-error nature of Roman engineering, as noted by project manager Simon Markus, who described the first well's failure as a setback that required considerable effort to overcome. The wells were remarkably preserved in waterlogged conditions, with one containing a nearly 2000-year-old ladder. The excavation site also contained evidence of metalworking and carpentry, indicating the area's transformation from a quiet farmstead to an industrial hub. This discovery underscores the Romans' advanced knowledge and adaptability in engineering despite occasional failures.
