Enclosing vast swathes of greenspace flanked by Hatfield to the north and Potters Bar to the south, sits the civil parish of North Mymms. Encompassing the areas of Brookmans Park, Welham Green, and Bell Bar - these small hamlets and villages are known for their grand country manor homes and farmhouses attached to significant acerage. With house prices averaging at over £1 million - North Mymms’ countryside aura and scenic landscapes are perfect for those looking for a quieter pace of life.

One of the most significant landmarks in North Mymms is the North Mymms Park - an historic 16th century country home at the heart of the civil parish. Now used as a wedding venue and filming location, this Elizabethan mansion house is the original manor house throughout the North Mymms parish. Originally purchased in 1316 by Simon Swanlond, the house changed hands several times before coming into the ownership of Elizabeth and John Coningsby in 1530, to which it stayed in the Coningsby family until 1658. One of the most intriguing elements of North Mymms Park is its artistic history - with a collection of rare tapestries and the 17th century mural of the ‘Nine Worthies’ found inside! Most of the surrounding villages and hamlets in North Mymms developed from the manor and boomed with the Victorian railway system.

There are some other curious oddities attached to this sleepy parish. Its often attributed, particularly to Brookmans Park, that the original ‘Little Miss Muffet’ nursery rhyme originated from this parish! Dr. Thomas Muffet, who lived with his family in Brookmans Park from 1553 to 1604, was an entomologist, who is said to have originally written this rhyme. Alongside this, he also discovered and catalogued the Mole Cricket in 1634 - a rarely seen insect!

Most of the North Mymms parish is covered in green belt land. Owing to this and the dispersed nature of the parish itself, development has often been slow and stagnant in the area. Part of the wider Welwyn Hatfield Borough Council (WHBC), the borough council has increasingly applied pressure - especially in the Welham Green locale - to create infill dwellings which would essentially join Welham Green to Hatfield South. Many local residents have fiercely resisted the plans for development on protected green belt land, however, as the local plans and recent developments have highlighted - infrastructural and housing development in the North Mymms parish is imminent. The WHBC has allocated provisions for the building of over 600 new dwellings throughout the North Mymms locale, and even a strategic business site providing over 40,500 sqm of business space!
