[2] The (antiquated) word möysä means a sauna doubling as a shelter, constructed in a partly underground hole.

It is presumed that the shores of lake Joutjärvi had numerous möysäs for use by travellers during the village of Lahti's time as a significant place of commerce during the 1600s.

[3] Möysä was traditionally part of the village of Järvenpää, which is presumed to be the oldest permanently inhabited area in Lahti.

It took until the 1800s for these residencies to spread from the eastern shore of Joutjärvi to the area that currently constitutes Möysä, towards the village of Lahti.

[4] As the Finnish army was split up and effectively absorbed by the Imperial Russian Army during the first period of Russification, the first Russian company to arrive in Lahti at the end of 1909 was temporarily housed in the Ionoff valenki factory in Möysä.
