A 2000-year-old Roman bridge has been discovered in Aegerten, Switzerland. Over 300 oak piles were unearthed, which have been preserved in the groundwater. Based on current dendrochronological analysis, the earliest construction dates back to approximately 40 BC, while the most recent parts are from 369 AD.
Archaeological excavation site showing rows of wooden posts or stumps emerging from the soil, the remains of the bridge. Some posts have small yellow markers placed on them. In the background, parts of the area are covered with plastic sheets for protection, with tools and a wheelbarrow visible at the edge of the dig.
Five large wooden stakes with pointed ends are laid out on a beige surface at an excavation site. A measuring scale runs alongside them for reference, and a small labeled marker is placed near the bottom right. The background shows dirt, rocks, and excavation tools.
