The municipality of Marin is located in the peninsula of Morrazo, on the southern shore of the Pontevedra Canal. The city centre is only 7 km away from Pontevedra. It has a population of 26,000 in an area of 35.9 km2. Fishing is its main economic activity. Its fishing port is the most important in both Galicia and Spain due to its depth and ease of mooring mooring, making it preferable to others such as Vigo, even in situations of adverse weather.
