Let's go!

SUMMARY

In this presentation, we’ll explore Seixal’s economic history. In the 19th and 20th centuries, Seixal became a key center for shipbuilding, textiles, and canning industries, providing employment and transforming the town into an industrial hub. Its strategic location by the Tejo River boosted trade and fishing. The river was vital for transporting goods, helping Seixal thrive as a shipbuilding site. These factors shaped Seixal’s modern economy, which still reflects its industrial roots while growing within the Lisbon metropolitan area.

history of the municipality of Seixal

In many respects, the municipality of Seixal was profoundly marked by industrialization, from the second half of the 19th century and throughout the 20th century, up to the present day, with deindustrialization. The territory was transformed, sometimes by demographic changes and lifestyles of the population, sometimes by the evolution of the landscape and urban reconfiguration, partly due to factories and industrial architecture.

A River-Based Economy

For centuries, Seixal’s economy depended on the Tagus River: Fishing (especially sardines and “peixe do alto”) Oyster farming and salt production Boat building and river transport The river connected Seixal to Lisbon, allowing goods and workers to move easily. This connection made Seixal attractive for factories.
