An architectural gem in the White Tower
The Chapel of St John the Evangelist in the White Tower at the Tower of London is a unique survival. It is the most complete surviving example of early Anglo-Norman royal ecclesiastical architecture.
The Chapel was built as a place of worship for William the Conqueror, but it was not completed until after his death. It was always intended to be spectacular, giving the worshipper the sense of being at the centre of a much larger church. Its imposing columns, carved capitals, high gallery and aisle for processions were built to impress.
Experience this grand space, where medieval kings and queens would have worshipped, at the top of the White Tower.

St John’s Chapel is one of the most beautiful spaces we have at the Tower of London, and it’s one of my personal favourite places within the fortress.

The History of St John's Chapel
The White Tower is a physical manifestation of power – even today it is humbling to stand at its base. In the 11th century though, it was the tallest building in London and would have dominated the surrounding landscape. St John's Chapel is an integral part of this landscape. It is set within a semi-circular projection — known as an apse — on the eastern face of William's keep.
This apse, which is typical of ecclesiastic architecture, would have sent a powerful message to all who saw it; it made clear that the Normans were God-fearing Christians as well as mighty warriors. It is one of the many features of the White Tower built to show the power of the new King.
The inclusion of a chapel also tells us that the Tower of London was built for domestic purposes as well as defensive ones. St John’s Chapel was the monarch’s private place of worship at the Tower.
Kings would have used this space for private worship accompanied by their chaplains and household. It may also have been used by early Constables of the Tower (known originally as Keepers) who looked after the Tower for the king. Over the centuries it was witness to some truly historic and spectacular events.

Key Moments
Simon Sudbury and the Peasants Revolt
During the Peasants Revolt of 1381, a mob seized Simon Sudbury, the Archbishop of Canterbury in St John’s Chapel where he was at prayer. Sudbury was dragged to Tower Hill, where he was executed.
Knights of the Bath ceremony
Before coronations, Knights of the Bath were invested in St John's Chapel. These knights had the honour of escorting the monarch on their procession to Westminster.
The ceremony of investiture in the Chapel included ritual bathing and an all-night prayer vigil. After being bathed, which was a symbolic act of purity, prospective knights processed into the Chapel and kept a prayer vigil all night, before accompanying the monarch to the coronation.
The Chapel was used for this ceremony from 1100 until about 1312 when it was converted for use as a record store. At this point it is likely that the ceremony would have taken place in a chapel built by Edward I on the site of the current Tudor Chapel of Saint Peter ad Vincula.

From Royal Chapel to State Storehouse
Despite its grand appearance and long-standing use as a royal place of worship, the Chapel soon ceased to be used for its original purpose. New private chapels were constructed within the medieval palace, to the south of the White Tower on the banks of the River Thames.
From at least 1312, St John's Chapel was used to store for important state records, and it was still being used in this way until the 19th century.
Consecration in the 19th century
Following the removal of the records to a new office in Chancery Lane in 1858, Prince Albert, Consort to Queen Victoria, lobbied for St John’s Chapel to be restored. The architect Anthony Salvin removed the historic bookshelves opening the space once more. In 1877 a stone altar, carved in Romanesque style to match the chapel, was installed – completing the work.
Today, the Chapel is an active place of worship and is used for services and celebrations by the Tower community under the Tower’s resident Chaplain.

The ‘Valasse Cross’ in St John’s Chapel
From March 2025 to January 2026, the magnificent Valasse Cross will be on display at the Tower of London. This beautiful cross is a rare example of medieval royal goldsmiths’ work. The larger outer cross was probably made in Normandy in the 1180s, around the same time as the Coronation Spoon in the Crown Jewels. The smaller, older cross at the centre is associated with Empress Matilda, granddaughter of William the Conqueror. It was likely made in the 1000s.
According to tradition the cross was owned by Valasse Abbey, which Empress Matilda (1102–67), founded in Normandy. Matilda was almost the first ruling Queen of England after her father named her heir. Matilda’s cousin Stephen seized the throne, beginning a civil war known as the Anarchy. Matilda was never crowned but secured the throne for her son, the future Henry II. Henry likely gifted the cross to Valasse Abbey.
The cross may have been carried in religious processions or used as an altar cross. The cross contains a relic of the ‘True Cross’, set at the front in wax. Relics were an important part of medieval religion. Medieval English kings and queens had large collections of relics which were used in ceremonies in chapels like St John’s.
The ‘Valasse Cross’ is a special loan from the Musée des Antiquités (Rouen Métropole Normandie) in France. The loan has been made possible thanks to the generous support of The Syder Foundation.
