Prince Henry's Room

Prince Henry's Room is a engineering topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Prince Henry's Room rather than just read about it. In short: Prince Henry's Room is situated on the first floor at the front of No. 17 Fleet Street, London. The house is one of the few surviving buildings in the City of London dating from before the Great Fire of London in 1666.

Key takeaways

  • Prince Henry's Room belongs to engineering; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Prince Henry's Room to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Prince Henry's Room from memory before moving on to harder problems.

Reference excerpt

Prince Henry's Room is situated on the first floor at the front of No. 17 Fleet Street, London. The house is one of the few surviving buildings in the City of London dating from before the Great Fire of London in 1666. It is a Grade II* listed building.

History The site was once owned by the Templars, but after the dissolution of the Order of St John, the building was rebuilt in 1610 and became a tavern called Prince's Arms. This coincided with the investiture of Prince Henry, son of James I, as Prince of Wales. During the 17th century, the house was known as the Fountain Inn and was visited by Samuel Pepys on 14 October 1661. He wrote "In the afternoon Captain Ferrers and I walked abroad to several places; among others, to Mr. Pim's my Lord's tailors and there he went out with us to the Fountain tavern and did give us store of wine." On 28 November 1661, Pepys wrote "to the Fountain tavern and there stayed till 12 at night, drinking and singing, Mr. Symons and one Mr. Agar singing very well. Then Mr. Gauden, being almost drunk, had the wit to be gone; and so I took leave too" Lord Thurlow frequented the place before he went on to practise law in the 1770s. It later became a hairdresser's and a plaque used to state it was once the home or palace of Henry VIII also Cardinal Wolsey lived there. The enriched ceiling was plastered with a"P" triple plumed. Once the Management of the Duchy of Cornwall held their sittings here in the time of Charles I, on or about 1619 (see Mrs Green's "Calendar of State Papers"). During the early 19th century a famous exhibition Mrs Salmon's Waxworks was held in the front part of the house, whilst the tavern continued in the rear. The house became the property of the London County Council in 1900 with the aid of a contribution from the City of London Corporation. It later passed to the City of London Corporation. From 1975, the room was a museum which hosted a Samuel Pepys exhibition — Pepys was born in Fleet Street in 1633. The Samuel Pepys Club financed much of the original exhibition. The museum was closed to the public after a decade or so and is now empty of all furniture. The building now houses the offices of the Delegation of the Catalonian Regional Government to the UK. Prince Henry's Room is currently only viewable when special events are held there. It was opened to the public for one day for the September 2023 London Open House Festival and received over 700 visitors. The City of London Corporation has recently completed a consultation with interested parties regarding the room's usage.

Architectural features The main feature is the fine and rare highly decorated Jacobean plaster ceiling, with the Prince of Wales's feathers and the initials "PH" in the centre. There is one wall of original Jacobean wood panelling left; the other panelling is Georgian. The unexceptional fireplace has a wood surround and panelling above, with an inscription above recording the connection with the diarist and great naval administrator, Samuel Pepys. There are also fine leaded lights with coats of arms and badges, best seen from within the room.

Worked examples

Example 1 — a first encounter with Prince Henry's Room

Start with the simplest possible case. Write down what Prince Henry's Room claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In engineering, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Prince Henry's Room before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Prince Henry's Room ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Prince Henry's Room

In research
Prince Henry's Room appears in engineering research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Prince Henry's Room in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Prince Henry's Room is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1610 establishments in England, Buildings and structures completed in 1610, Buildings and structures of the Knights Templar, so understanding it makes those chapters shorter.
In everyday life
Look for Prince Henry's Room outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
