The Maritime History of Blanes: From Ancient Roman Port to Costa Brava’s Nautical Gateway

How a 2,000-year-old fishing village became one of the Mediterranean’s most authentic coastal destinations — and why exploring it by boat is the best way to experience its heritage.

If you’ve ever looked at a map of Spain’s northeastern coast, you might have noticed the dramatic shift where golden sandy beaches give way to rugged cliffs, hidden coves, and crystal-clear waters. That transition point has a name: Blanes.

Known as the gateway to the Costa Brava, Blanes sits at the exact spot where one of Europe’s most spectacular coastlines officially begins. But while most visitors come for the beaches, few realize they’re stepping into a town with over two millennia of maritime heritage.

Human settlement in Blanes dates back to the Iberians, but it was the Romans who truly put it on the maritime map. The ancient settlement of Blanda was already an active trading port by the 2nd century BC. Archaeologists have recovered Roman amphorae from the seabed — evidence of busy trade routes connecting the Iberian Peninsula with Rome and North Africa.

The geography made it inevitable. Blanes sits in a natural bay, sheltered from the fierce tramontana winds by surrounding mountains. For ancient sailors, it was the perfect safe harbor. High above the town, the ruins of the Castle of Sant Joan (13th century) stand as a reminder of less peaceful times — a watchtower against pirates with extraordinary views stretching from Cape Tossa de Mar to the Gulf of Roses.

Unlike many Mediterranean towns that have traded their fishing heritage for tourism, Blanes has held onto both. Its fishing port remains one of the most active on the Costa Brava. Every afternoon around 5:00 PM, the llotja (fish auction house) comes alive with a lively auction where local restaurants bid for the freshest catch — including the famous gamba roja, a red prawn caught at depths of 400 to 600 meters, considered one of the finest seafood products in the western Mediterranean.

The lighthouse of Blanes sits beside Sa Palomera, the iconic rocky promontory that marks the official boundary between the Costa del Maresme and the Costa Brava. And on the cliffs above Cala Sant Francesc, the Marimurtra Botanical Garden — founded in 1921 by German botanist Karl Faust — houses over 4,000 plant species on terraces overlooking the Mediterranean, making it one of the most important botanical gardens in the region.

Like much of the Costa Brava, Blanes underwent a dramatic transformation in the 1960s when mass tourism arrived in Spain. But unlike many coastal towns that surrendered entirely to uncontrolled development, Blanes maintained a remarkable balance. Its old town preserved its maritime character, the fishing port stayed active, and local traditions survived the tourist wave. Today, the focus has shifted toward quality tourism centered on nature and authentic experiences, with nautical tourism becoming a key part of this new chapter.

Blanes’ connection to the sea is also celebrated throughout the year. The Fiesta de Santa Anna in late July features an international fireworks competition launched from Sa Palomera rock over the sea. During the patron saint festivities, a maritime procession carries the image of the Virgin del Carmen across the water, accompanied by the fishing fleet in full regalia. And the annual Gamba Festival celebrates the town’s star product with special menus, cooking demonstrations, and events centered around the port.

There is something profound about approaching Blanes from the water. You see the same coastline that Roman merchants saw, the same castle that once watched for pirates, the same cliffs where Karl Faust planted his garden over a century ago. When you sail from the port of Blanes, you are not just renting a boat. You are joining a maritime tradition that spans over 2,000 years.
