The area of Keilaniemi, Espoo has a major role in Finnish business life with headquarters of four major companies: Nokia, Kone, Elisa and Fortum.
The highest of the buildings (Fortum HQ) is still known as "Raaden hammas" according to the former company CEO Uolevi Raade. After the Nokia HQ was build, it was named using the same method as "Ollilan jorma". If you're familiar with similar names for the rest of the buildings, please post them here.
