Marín has been a First Class maritime district since 1868 and has the service of numerous European and South American consulates because of the significant commercial and migratory movement. It has a large bay that extends from Pesqueira Point to Placeres, and its value as a maritime communication route dates back to Roman times.
The estuary of Pontevedra began its commercial and industrial take-off in the mid-18th century when salting and canning industries established in the area, as well as other maritime activities.
