Tietgenbyen

Tietgenbyen is a industrial area in Denmark situated southeast of Odense near European route E20. It is named after C.F. Tietgen, a businessman born in Odense.
The industrial area was established in 1999 by Odense municipality. Business had long advocated for an industrial area near the highway. In its early years, it had difficulties attracting new companies and only sold in 1999 and 2000, but managed to reach its unofficial goal of selling at least within 12 years. In January 2017, Tietgenbyen contained 75 companies, and most of its lots had been sold. An area north of Tietgenbyen, known as Tietgenbyen Nord, has been reserved by Odense Municipality for future expansions. The new land is privately owned, so it has to be bought by the municipality before it can be used industrially.
Tietgenbyen contains a data center owned by Facebook, with an area of 56,500 square meters. A district heating system is established in connection with the data center, distributing surplus heat to 7,000 houses (planned to be extended to 12,000 houses). The plans to build the data center were first revealed by "Fyens Stiftstidene" in October 2016, and confirmed by Facebook and Odense municipality in January 2017. The data center is Facebook's third data center outside the United States. It started operating in September 2019, although only partially. According to "Fyens Stiftstidende", Facebook is ready to extend the data center with a third server building, in addition to the two already built, and is considering building two more.
A number of robotics firms are located in Tietgenbyen, including Universal Robots, Jorgensen Engineering, and ABB.
Archeological excavations prior to the establishments of Tietgenbyen have found a number of settlements from the bronze age in the area.
