1. About Barrage du Port Melin
- Type: Hydraulic dam 🏗️
- Location: Groix, Brittany, France (47.647219 N, -3.472262 W)
- Dimensions: 70 m long, 18 m high

Constructed in the late 1960s, the Barrage du Port Melin was part of a regional effort to regulate water flow for agricultural irrigation and local water supply on the island.

Why it matters: Beyond its functional role, the dam symbolizes Brittany’s balance between preserving natural beauty and embracing modern infrastructure. It’s a tangible reminder of how the region harnesses its waterways without sacrificing the charm that draws visitors from around the world.
