Lokalahti was originally the name of a long bay of the Baltic Sea, reaching out to the village. The bay no longer exists due to the
post-glacial rebound in the area, it is now the lake
Ahmasvesi and the nearly closed-off Kuutniemenaukko bay. Lokalahti was originally a part of the
Vehmaa parish. Lokalahti already had a chapel in 1409. It became an independent parish in 1630, but rejoined Vehmaa in 1690. Lokalahti became independent again in 1905, remaining independent until it was consolidated with the town of
Uusikaupunki in 1981. The Lokalahti parish became one of Uusikaupunki's areal parishes in the process. == Church ==
