Consecrated as a Great Sampford chapel of ease in 1365. The 15th century chancel was extended in Tudor brick. The tower collapsed in1882, and the aisle walls had to be rebuilt in 1887 as part of a major restoration. The tower however had to wait until 1933 to be rebuilt. The church is littered with various monuments to the Harvey family, who were the big cheeses in this part of Essex for centuries, including Sir William Harvey, physician to Charles I and inventor of blood circulation.
