St Mary's has been the parish church for the local community since the early 1300s, although records show the first rector as Thomas de St. Albans, appointed in 1237. Our friendly church is situated in a rural setting, on the edge of North Mymms Park. It is a quiet oasis off the busy A1 (M) serving the communities of Brookmans Park and Welham Green.

You can find us on the extension of Dixon's Hill Road, which is the road going towards Colney Heath and St. Albans from Welham Green. Welham Green is the location of St. Mary's Church of England Primary School which has close links with the church. You can find further information about the school on their website.

2005 saw North Mymms becoming part of the Bishop's Hatfield Team Ministry together with the four Anglican Hatfield Churches and St. John's the Evangelist in Lemsford.
