Oostende, was nothing more than a small village built on an island between the North Sea and a beach lake. Although small, the village rose to the status of 'city' around 1265 when the inhabitants were allowed to hold a market and to build a market hall. The North Sea coastline has always been rather unstable and in 1395 the inhabitants decided to build a new Oostende behindlarge dikes and further away from the always threatening sea.

The strategic position on the North Sea coast had major advantages for Oostende as a harbor but also proved to be a source of trouble. The city was frequently taken, destroyed and rampaged by conquering armies. After their independence from the Spanish Empire, the Dutch had preserved some strongholds in the Southern Netherlands, such as the cities of Nieuwpoort and Oostende. Between 1601 and 1604 the Spanish army succeeded in taking Oostende from the Geuzen.

After this era Oostende turned into a quiet harbor of some importance. In 1722 the Dutch closed off the entrance to the harbor of Antwerp. Therefore, Oostende rose in importance because the city provided an alternative entrance to the sea. The Southern Netherlands had became part of the Austrian Empire. The Austrian Emperor Charles VI granted the city the trade monopoly with Africa and the Far-East. The 'Oostendse Compagnie' = the Ostend trade society was allowed to found colonies overseas.

In later times the harbor of Oostende continued to expand because the harbor dock, as well as the traffic connections with the hinterland were improved. In 1838 a railway connection with Brussels was constructed. Oostende became a transit harbor to England in 1846 when the first Ferryboat sailed to Dover. Very important for the image of the city was the attention it started to receive from the Belgian kings Leopold I and Leopold II. Important monuments and villas were built to please the Royal Family. The rest of aristocratic Belgium followed and soon Oostende became known as "The Queen of the Belgian sea-side".

Nowadays Oostende is a city of about 90.000 inhabitants and still the largest city at the Belgian coast.
