The church was rebuilt in 1275.

By 1509 the central tower was causing concern, and was taken down. A new tower was completed in 1522, and the pinnacles were added in 1755. The tower now contains a peal of thirteen bells.

In the early 1990s, repairs were carried out to the roof and interior plasterwork. The green glass, installed in the Victorian restoration, was replaced with the clear Georgian glass you see today, and the “temporary” wooden rostrum below the chancel steps (which had been with us for some thirty years) replaced by a fine stone plinth.

The reredos was moved westwards to its present position, making space for the Sacristy, ambulatory and choir vestry under the east window. This vacated the north chapel, allowing an unobstructed view of the Shelburne memorial, carved by the Flemish sculptor, Peter Scheemakers in 1754.

A little known feature of All Saints is that William Petty the 2nd Earl of Shelburne, who was Prime Minister of England, July 1782-April 1783, is buried in its vaults. In 1761, having briefly served as MP for Wycombe, he succeeded his father as Earl of Shelburne. Following his resignation as Prime Minister he was created Marquis of Lansdowne and Earl Wycombe. He lived at Loakes (now known as Wycombe Abbey) from 1761 until he retired in 1784 to his other seat, Bowood in Wiltshire.

Following his death at Lansdowne House, Berkeley Square, London he was buried in the family vault in the North Chancel Chapel of All Saints Parish Church on 14 May 1805.

Whilst there is a record in the burial register and a description of his coffin and funeral cortege in the Gentleman’s Magazine there is no memorial in the church to him.

The entrance to the vault was tiled over by Street in the 1873-5 restoration of the church. So its exact position is not marked though it is known to be under the great baroque monument erected to Henry Petty, which included an enlarged family vault beneath.  The monument by Scheemakers depicts Henry, reclining on a sarcophagus surrounded by his family who pre-deceased him. The Earl and Countess and some of their children are buried in the vault beneath.
 

William’s first wife, Lady Sophia Cartaret, died aged 25. She is commemorated in a heroic marble monument by Carlini in the South (Lady) Chapel, commissioned by the Earl.

It depicts her in classical mode with her two adoring sons. Sophia and her youngest son, and Shelburne’s second wife are also buried in the family vault.
 

The lack of a memorial to the Marquis is a bit of a mystery. He had fallen out with his eldest son, and had espoused unpopular polices. He was best remembered for the loss of the American Colonies, unfair though that was.

In fact he was responsible for the Treaty of Paris, 1783, which gave the United States its independence and provided a just settlement that suited the interests of both sides.

There is a modern coloured glass window near the Shelburne Monument which commemorates the role of the Earl and Benjamin Franklin in the negotiation of the Treaty.
