Medieval harbours The first port of Bremen was the
Balge, a narrow branch of the
Weser river. In the mid-13th century, on Bremen city's riverside of the main river, a quay was built, called the
Schlachte. For about three centuries, both ports were used in parallel, before Balge harbour stopped being used.
Outer Harbours Like in many other European regions, the medieval extension of agriculture increased erosion of soil in the Weser basin. Since about 1400, the bed of the lower Weser was choked with sand, dramatically. Laden sea vessels could no longer run upriver to Bremen city. Ships were discharged on riverboats in the open lower Weser. In 1622/23, Bremen's first outer harbour was founded in
Vegesack, 20 km downstream of Bremen. Soon it was lacking depth, too. Finding a more durable outer harbour site was difficult, as the neighbouring territorial states preferred to patronize their own ports. Finally in 1827, the
state of Bremen succeeded to buy the ground of the relics of
Swedish foundation
Carlsburg on the mouth of the
Geeste river into the
Weser estuary. In 1830 the first port of Bremerhaven was opened.
Emigrants In 1832, Bremen passed a law for human standards for emigrant passengers in overseas traffic. For some decades the ports of Bremen became the most important emigrant harbour of central Europe.
Weser Correction and modern basins After Bremen in 1847 was linked to the
Royal Hanoverian State Railways, the Bremish state built its own short railway line from the (Hanoverian) station to the bank of the river Weser near the edge of the old city. The goods station on the new quay, called
Weserbahnhof, was one of the most modern links between land transport and sea trade of that age. In the last quarter of the 19th century, a way was found to employ the help of natural powers to use the lower Weser as an efficient waterway for modern sea vessels.
Ludwig Franzius, building superintendent of Bremen, recorded the hydrology of the lower Weser for several years. In 1881, he published a convincing project. In 1887 to 1895, works were done under his management. In the meantime, in Bremen city some modern basins were built. When in 1888 the state of Bremen joined the
German Customs Union, the
Europahafen became a
free port that was later enlarged by other new basins.
Since mid 20th century Over the last decades, the ports of Bremen have seen the same developments as most other ports of the world: • Overseas passenger traffic has switched to
air transport. • Mixed cargo has been displaced by container transport. • The increase of the size of sea vessels. The reactions were: • In 1964, Bremen's first container port was opened, the
Neustädter Hafen. • Since the 1970s, a line of
container terminals were built north of the older ports of Bremerhaven, on the bank of the Weser estuary on the edge of the open sea. • The
Überseehafen, which opened in 1906, was taken out of service in 1991. In 1998, the basin was filled up with soil excavated in the maintaining of the shipping lane of outer Weser estuary. This reclaimed land has provided space for a new urban district, called
Überseestadt. == List of basins and other sites ==
