De Bosset Bridge, Stone bridge in Argostoli, Greece.
De Bosset Bridge stretches roughly 690 meters across the Koutavos Lagoon with 16 low stone arches arranged in a double curve design. The curved layout helps water flow beneath the structure while pedestrians today use the pathway to cross between Argostoli and the Tampakika coast.
Swiss engineer Charles Philip de Bosset built a wooden bridge across the lagoon in 1813 under British command. The structure was later rebuilt in stone to provide greater durability in the marine environment.
A marble obelisk at the bridge's center displays inscriptions in four languages honoring the British role in its construction. Visitors walking across notice this memorial, which ties the structure to the island's colonial past and international connections.
The pathway is straightforward for walking and offers clear views across the lagoon from both sides. Visitors should take time to enjoy the surroundings during the crossing and be aware that the route can be exposed to weather conditions.
This structure ranks among Europe's longest stone arches over seawater, stretching nearly 690 meters end to end. Its unusual double-curve design was technically advanced for the early 1800s and solved specific challenges of building over shifting lagoon waters.
