Aitolahti (Finnish pronunciation: [ˈɑi̯tolɑhti]; now forms the Tampere subdivision under the name Aito) is a former municipality in Pirkanmaa region, Finland.

[2] When the Aitolahti became independent parish after leaving Messukylä, there were only about 600 inhabitants, and the population grew very slowly for a long time, until growth accelerated in the 1950s.

[2] At the end of the 19th century, the Finnish geologist J. J. Sederholm discovered oval-shaped depressions in the shore cliffs and rocks of Lake Näsijärvi, which he called Corycium enigmaticum, "enigmatic carbon bags".

These are remnants of rudimentary microbial activity about two billion years ago and have been found in the rest of the world only in South Africa and Canada.

[3] In the 1980s, pork soup and barley groat porridge with buttermilk were named traditional dishes of Aitolahti parish.
