About Harmer Green, Hertfordshire

Harmer Green retains a quiet, unassuming composure, defined by the narrow lanes that wind through the Hertfordshire landscape like frayed ribbons. It lies 2.3 miles north-north-east of Welwyn Garden City (from Welwyn Garden City: bearing 33°T, OS grid TL 257 163), and is situated west-south-west of Burnham Green village. The light here often catches the flint-strewn verges, casting long, sharp shadows that seem to anchor the houses firmly against the shifting seasons. A short distance to the north-north-east, the Linear Earthwork In Perry's Grove traces an ancient, silent boundary through the woodland, reminding the observant walker of lives lived long before the modern tarmac. Harmer Green possesses a stubborn independence, resisting the encroaching sprawl of its neighbours by clinging to a topography of modest dips and sudden, leafy rises. To the south, the expansive grounds of Tewin Water offer a different character, where the air feels heavier and cooler near the managed parkland. These surroundings do not clamour for attention, but rather offer a steady, rhythmic presence to those who travel the quiet paths connecting one homestead to the next. Even in the greyest of months, the robust brickwork of the older dwellings provides a warmth that defies the damp, biting air of the Eastern region.
