History

Perspective

The history of Janakkala stretches far back to prehistoric times, as evidenced by numerous archaeological finds and traces of settlement. The area has been inhabited at least since the Stone Age, and especially the Vanajavesi valley and the Laurinmäki region have served as centers of human habitation for thousands of years. Several significant Iron Age burial sites and sacrificial stones have been found in Janakkala, including a Viking Age cremation cemetery discovered in 2016. The area also features hillforts, with the most famous being Hakoisten Linnavuori, which once served as an important place of refuge and a center of trade.[5][6][7][8]
Christianity gradually arrived in the Janakkala region from the start of the 9th century, although its official establishment took longer. Before the breakthrough of Christianity, Janakkala was part of the larger Greater Vanaja region, but it became a parish around the year 1300. The first written mention of Janakkala dates back to 1341, when Bo Joninpoika issued a judgment in Janakkala. During the Middle Ages, Janakkala became especially well known for its Hakoisten hillfort and manor houses. These manors have played an essential role in the life of the region for centuries.[5][8]
The Swedish era, beginning in the 13th century, marked a period when Janakkala became an important base for Swedish administration in Häme. The region's versatile waterways provided excellent conditions for trade and agriculture, and Hakoisten hillfort protected the settlement and its connections to other areas. The role of the church and administration grew significantly over time.[5]
Janakkala is renowned as a manor parish: it is home to many well-known manors, such as Hakoisten, Harviala, Hyvikkälä, and Vanantaa. For a long time, influential noble families resided in these manors, and manor life has left a lasting impact on the local culture and landscape.[5]
Industrialization began early in Janakkala compared to many other rural municipalities. The Tervakoski paper mill was established as early as 1818, growing into a significant locality. Leppäkoski, in turn, developed a strong identity through its brick industry, while the significance of the Turenki locality increased thanks to sugar and ice cream factories. The reform of municipal administration, which developed Finnish society, resulted in Janakkala becoming its own municipality under the 1865 decree.[5]
Janakkala's identity includes a strong connection to history and culture, which is still visible in its settlements, museums, and monuments: the Laurinmäki tenant farmer museum, old manors, Hakoisten linna and church, and many other historical sites all tell the story of a parish with a diverse and long history, from the Stone Age to the present day.[5][7]

Perspective


The development of industry in Janakkala began exceptionally early compared to other Finnish rural municipalities. The first significant industrial concentration formed in Tervakoski, where a paper mill was established in 1818. Initially, the factory operated with water power and used rags as raw material, but by the mid-19th century, production became mechanised and steam power was introduced. Over the years, the product range of the paper mill has varied, and at its peak, it produced cigarette and condenser papers as well as banknote paper. Tervakoski paper mill is the oldest continuously operating paper mill in Finland, and it still plays a central role in the region's economy, especially as a producer of specialty papers.[5]
The area of Leppäkoski, on the other hand, grew around the brick industry. The clayey soil here enabled large-scale brick production, which developed into its own local industrial tradition. Brick manufacturing had a strong impact on the structure and settlement pattern of the entire village of Leppäkoski.[5]
Another significant industrial area in the municipality is Turenki, where the railway had a decisive influence on the birth of industry and settlement. In the late 1940s, a sugar factory was established in Turenki, which triggered rapid development in the region. The sugar factory also enabled extensive sugar beet cultivation in Janakkala, and millions of kilos of sugar were produced annually during production seasons. Later, in the 1960s, an ice cream factory was built in Turenki, which continues ice cream production today (currently Froneri Finland). Although sugar production ended in 1998, the former factory buildings are still used for industrial and business purposes.[5][9]
Janakkala still has a diverse industrial structure: it is home to companies in the food industry (Valio and Froneri), metal industry (such as Kolmeks Oy's pump and motor manufacturing), and even musical instrument makers. The municipality is located in a logistically central area of Southern Finland, which has contributed to the establishment of over 900 companies. Expanding business parks, such as MORE (one of the largest in Southern Finland), continue to offer facilities for industry and logistics. Janakkala's industrial history is clearly visible in both the landscape and the economic structure, and various industries still form an important part of the municipality's identity and employment.[5][10]
