'Mäntsälä church village') is the largest urban area and the municipal center of Mäntsälä in Uusimaa, Finland, with about 11,000 inhabitants.
The village name Mäntsälä appears in early written material in the form Mensela, Menselä, Mensilä (1458), Mensse (1516), Mentzeby (1540).
[2] The village name has evolved from the house name, which probably includes the early host's first name Mäntsä (or Mänssä).
According to Viljo Nissilä, a possible starting point may have been the male name Menze (or Mensse), found in the Friesland area.
The current Highway 4 runs as a motorway past the church village, but the old road between Helsinki and Lahti, the current regional road 140, runs directly through it and serves as the main street in the urban area.
