Evaluating Evidence for Kenilworth Castle's Layout

Reconstructing a castle that changed over time

Kenilworth Castle’s present ruins are not a complete picture of its medieval or Elizabethan appearance. Buildings were added, altered and removed over centuries. Its fortifications were dismantled in 1649–50, and the great man-made lake, or mere, was subsequently drained. Historians therefore combine written records, plans, drawings, photographs and the surviving fabric to reconstruct its layout at different times.

The starting point is a precise question. Evidence useful for asking ‘How are the surviving buildings arranged?’ may be less useful for asking ‘What surrounded the castle in 1575?’ Evaluation means explaining what evidence helps us establish, where its limitations lie and how other evidence can test the conclusion.

Contracts: evidence of intended building work

A building contract records an agreement to carry out work. Depending on its contents, it can identify the people involved, the proposed building, materials, dimensions, costs or deadlines. Such details can help historians connect a change in layout with a particular patron and purpose.

At Kenilworth, John of Gaunt’s great hall was built between 1373 and 1380 as part of his ambitious rebuilding. For an enquiry into that project, a contract specifying the hall’s dimensions or materials would be valuable evidence of what was commissioned. However, an agreement alone would not prove that every detail was completed: plans could change, work could be delayed or a project could remain unfinished. Historians would compare its provisions with payment records and surviving masonry.

This distinction matters because intention is not the same as outcome. Documentary detail and physical evidence answer different parts of the same question.

Plans: understanding arrangement rather than appearance

An architect’s plan can show where rooms, walls, entrances and passages were intended to go. Unlike a view of a building from outside, a plan helps reveal connections: which entrance leads into which court, and how one group of rooms relates to another.

First establish whether a plan is a proposed design, a survey of an existing building or a later reconstruction. Check its date, labels, scale and key. A design records intentions; a measured survey records what could be observed when it was made; a reconstruction combines evidence with interpretation. They should not be treated as interchangeable.

Kenilworth’s southern approach illustrates the kind of relationship a plan can clarify. The causeway leads towards Mortimer’s Tower, the main medieval entrance. The causeway initially acted as a dam for the mere and later also served as a tiltyard for jousting. A plan can make this route easier to follow, but its date is crucial: a modern survey cannot, by itself, establish the extent of the former lake or the appearance of buildings that have disappeared.

Drawings: recovering features that no longer survive

Contemporary drawings can preserve evidence of rooflines, towers, entrances and water features later lost. Their value depends partly on whether the artist observed the site directly and what the image was intended to do. A view intended to impress might emphasise grandeur; a distant viewpoint might conceal buildings behind others. Apparent proportions are not necessarily accurate measurements.

A useful Kenilworth example is the image representing the castle in 1620, known through a nineteenth-century copy of a lost seventeenth-century wall-painting at Newnham Paddox House. It represents the castle with its mere and pools before the dismantling of 1650. It is therefore relevant to reconstructing a landscape that a modern photograph cannot record.

Its transmission also limits confidence: the surviving copy was not made in 1620, and copying introduced another opportunity for alteration or error. Historians must distinguish the date of the scene from the date of the surviving image, then check its representation against documents, archaeology and remaining structures.

Reading an aerial photograph of Kenilworth

An aerial photograph records the visible site at a particular moment. It is especially useful for seeing buildings together with open ground, vegetation and neighbouring settlement.

In this 2018 photograph, the castle ruins form a compact group in the lower central part of the view. Tall, roofless walls rise within lower enclosing walls; open grassland lies in the foreground, while streets and housing spread behind the castle. These observations help establish the relationship between the surviving castle, surrounding open land and the modern town.

The photograph is taken at an angle rather than vertically overhead. Nearer walls can hide structures behind them, trees obscure parts of the site, and there is no scale from which to measure distances accurately. It is useful for broad relationships, not precise room dimensions or identifying every building phase.

The open land around the ruins must not be mistaken for the medieval landscape. Historical evidence establishes that Kenilworth once had a large mere, later drained. The photograph records the landscape in 2018; it does not establish the former water’s boundaries or depth. Nor does a photograph of damaged walls alone explain when or why the damage occurred.

Building a stronger interpretation

Historians gain confidence when different types of evidence agree. Robert Langham, an official in Leicester’s household, described the garden prepared for Elizabeth I’s visit in 1575. He had access to it while the queen was away hunting. Archaeological investigation has supported the accuracy of his account, and both forms of evidence informed the modern recreation of the garden.

This provides a concrete model of corroboration: an eyewitness description supplies details that buried remains may not preserve, while archaeology tests aspects of the description. The recreated garden is an interpretation based on evidence, not an untouched survival from 1575.

A strong conclusion therefore explains both what can be reconstructed confidently and what remains uncertain. Combining evidence is more convincing than assuming that one detailed document or realistic-looking image tells the whole story.

Match evidence to the enquiry

• Contracts: intended work, responsibilities and specifications; do not prove completion.
• Architects’ plans: intended arrangement; distinguish designs from measured surveys and later reconstructions.
• Contemporary drawings: appearance and vanished features; check viewpoint, purpose, proportions and whether the surviving image is a copy.
• Aerial photographs: surviving layout and landscape at the photograph’s date; limited by angle, obstruction and lack of scale.

Kenilworth anchors

• Great hall, 1373–80: John of Gaunt’s building project; compare documentary evidence with surviving fabric.
• 1620 view: survives through a nineteenth-century copy of a lost seventeenth-century wall-painting; relevant to the mere and pools before dismantling.
• 2018 aerial photograph: surviving ruins, open land and modern town—not the medieval landscape.
• 1575 garden: Langham’s description checked against archaeology; the present garden is a recreation.
