History

Lieto Cooperative Store in 1934

Map of the municipal mergers of Lieto and Aura. The main part of Aura was previously part of the Prunkkala chapel parish under Lieto. Tarvasjoki municipality was merged with Lieto in 2015.

Archaeological findings in Lieto indicate that the area has been inhabited since the Stone and Bronze Ages. Vanhalinna of Lieto is one of Finland's ancient hillforts. Numerous Iron Age and medieval artifacts have been discovered in the hillfort area of Vanhalinna.

A document from 1331 survives in which Lieto's parish priest, Pietari, is mentioned for the first time. As a result, the founding year of the Lieto parish and church is considered to be 1331.

In June 2014, the Government of Finland decided, under the 2013 municipal structure law, to merge Tarvasjoki with Lieto. The merger came into effect on 1 January 2015.^[11]

In May 2022, the municipal council of Lieto decided to adopt the status of a town.^[12] The proposal was made by municipal manager Mika Ingi, who argued that city status could improve Lieto's position within the new wellbeing services county.^[13]

In 2016, the largest corporate income tax payers in Lieto were Liedon Säästöpankki (Lieto Savings Bank), I.S. Mäkinen Oy, a company specializing in cruise ship interiors, and Carrus Delta, a manufacturer of bus bodies.^[14]
