In Jyväskylä region, there are archeological findings from the Stone Age and cultivation had already started 3500 years ago. According to the oldest available taxation documents (maakirja) there were seven estates in the Jyväskylä region in 1539. One of them, the estate of Mattila, alone possessed the areas stretching from the village of Keljo to the villages of Vesanka and Palokka. The oldest estate in Jyväskylä that has been held continuously by the same family is the estate of Lahti which emerged when the estate of Mattila was split for two brothers in 1600. The history of the estate of Lahti and the family of Lahti has had a significant impact on the development of Jyväskylä region. Lahdenrinne in the south-west corner of Jyväsjärvi lake belongs to the old heartland of the estate of Lahti.
The City of Jyväskylä was founded on 22 March 1837 by Czar Nicholas I of Russia and the infrastructure was essentially built from scratch. The original town was built between Lake Jyväsjärvi (which is connected to Lake Päijänne) and the Jyväskylä ridge (Harju), and consisted of most of the current grid-style city centre.
The establishment of schools in the 1850s and 1860s proved to be the most important step from the point of view of the later development of Jyväskylä. First three Finnish-speaking schools in the world were founded in Jyväskylä, the lycée in 1858, the teachers’ college in 1863, and the girls’ school in 1864. Well-trained teaching staff and pupils from different parts of the country changed the atmosphere of Jyväskylä irrevocably.
In the early 20th century, the town expanded several times. Most of today's Jyväskylä was built after the Continuation war, when refugees from Karelia and other parts of the country moved to the city and housing was badly needed. During 21st century Jyväskylä has grown fast – by over 1,000 inhabitants every year.
Säynätsalo was consolidated with Jyväskylä in 1993
