The church at Bygrave has been closed every time I have walked through. Parts of it date from the 12th century but there was a Saxon church there before and Romano-British pottery has been found around the site. It is tiny, unusual in its simplicity, and rather beautiful for that. The bell is located in a tiny housing. The hamlet is of interest, a handful of houses around three farms on a hill surrounded by the flat lands north of the Chilterns extension east of Baldock. The land was never enclosed and the farms have taken over what were three enormous medieval open fields.
