History of Strasbourg in a few lines:
Origins:
Strasbourg originated as a Roman settlement in the 1st century AD called Argentoratum, Established as a military fortress on the Rhine, its strategic position soon made it a key point for trade and defense.
Middle Ages:
During the Middle Ages, it developed as a prosperous free city of the Holy Roman Empire. It was a prominent center of crafts and commerce, and in 1439 saw the establishment of one of Gutenberg's first printing presses outside Mainz.
19th Century:
In the 19th century, Strasbourg passed from France to Germany after the Franco-Prussian War (1871) and underwent a profound urban transformation. After the First World War, it returned to French hands, marking its borderland and multicultural character.
Present:
Today, Strasbourg is a symbol of European cooperation. It is home to the European Parliament, the Council of Europe, and other institutions. Its historic center, the Grande Île, is a UNESCO World Heritage Site and combines Alsatian tradition with modern administration.
It's very pretty but not very big; you can see it quickly. The tree they put in the square really moved us.

Strasbourg combines very well with a visit to Obernai, especially if you're looking for typical villages, half-timbered houses and routes through the most traditional Alsace.
