[4] Letty Green, to the west, has a grade II listed deconsecrated St John's Church.

There are 11 cottars and 4 slaves, and 2 mills rendering 6s, meadow for 3 ploughs, pasture for the livestock of the vill and woodland for 200 pigs.

Mary's Church is situated on rising ground to the east of the village, overlooking the water meadows that lead down to the River Mimram.

Inside the church is some interesting alabaster work, including the pulpit, and oak carvings by a native of Oberammergau.

The churchyard contains the unmarked grave of Jane Wenham, erroneously believed to be the last person to be sentenced to death for witchcraft in England.

She was condemned by a Hertford court in 1712 but was given a reprieve from the death sentence and later granted a Royal pardon by Queen Anne.

[8] The Camden Town Group artist, Spencer Gore, whose mother lived in Hertingfordbury, was buried in the churchyard, after dying in Richmond.

An American heiress, Pauline Payne Whitney, who had married Lord Queenborough, is buried there as is their daughter, Dorothy Paget, a racehorse owner, whose horses won the Cheltenham Gold Cup seven times and the Champion Hurdle four.

A little to the south of the main village is "Roxford House" on St. Mary's Lane, a Grade II Listed Building, where Austrian composer Joseph Haydn stayed for the summer of 1791.

[10][11] The White Horse is a 15th-century Georgian-fronted building that in the past was a staging post for the Reading to Cambridge coach.

The station was the setting for scenes in the 1936 film When Knights Were Bold, and an ITV children's TV programme, Catweazle in 1970.
