History

The original coat of arms of Masku.

Masku is one of the oldest parishes in Finland, having been established in the 13th century. It included Merimasku until 1577, when it was transferred to Naantali.^[5] The people of Masku also once held hunting grounds in the Turku archipelago, as evidenced by the toponym Maskinnamo (originally *Maskun Innanmaa) in Korpo. There is also a village called Maskulainen in both Rymättylä and Lemu, suggesting that the first settlers of those villages came from Masku.^[6]

Lemu and Askainen were consolidated with Masku in 2009. Masku adopted Askainen's coat of arms after the merger.
