Tricorn Centre

Tricorn Centre 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 Tricorn Centre rather than just read about it. In short: The Tricorn Centre was a shopping, nightclub and car park complex in Portsmouth, Hampshire, England. It was designed in the Brutalist style by Owen Luder and Rodney Gordon and took its name from the site's shape which from the air resembled a tricorn hat.

Key takeaways

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

Reference excerpt

The Tricorn Centre was a shopping, nightclub and car park complex in Portsmouth, Hampshire, England. It was designed in the Brutalist style by Owen Luder and Rodney Gordon and took its name from the site's shape which from the air resembled a tricorn hat. Constructed in the mid-1960s, it was demolished in 2004. It was home to one of the first Virgin Megastores and housed the largest Laser Quest arena in Europe. The centre was a well-known example of 1960s architecture, and in the 1980s it was voted the 3rd ugliest building in the UK. In 2001, BBC Radio 4 listeners voted it the most hated building in the UK, and Charles, Prince of Wales described it as "a mildewed lump of elephant droppings". Demolition of the Tricorn began on 24 March 2004 and took approximately nine months. As of 2024, the site is a ground level car park for the city centre.

Construction and opening

Opened in 1966, the centre was an attempt to revitalise Portsmouth, costing the city council £2 million. Originally called 'the Casbah' by its creators, it was deliberately designed with vast amounts of blank surfaces with the expectation that tenants would provide the colour and character via their signage and store frontages. It was hoped that premium stores would occupy the centre but as the centre was not connected to Portsmouth Town Centre, these stores never moved in. Instead the units were let to smaller stores. As well as small traders, tenants included a supermarket and two pubs. In 1967 the site received a commendation from the Civic Trust.

Businesses in the Tricorn With the failure of a large store to move in, most of the shops were small traders of various types, including market traders with a range of stalls. There was also a Fine Fare supermarket. The council succeeded in getting the fruit and veg market to move from Commercial Road but there were soon complaints. Conditions were found to be dark, damp and poorly ventilated. Access was also a problem with lorries finding it difficult to get to the market via the spiral ramps.

Pubs Two pubs – The Casbah and The Golden Bell – were located inside the Tricorn Centre. They were officially opened on 31 August 1966. There was also a club for live music – originally named the Tricorn Club, later renamed Granny's and subsequently Basins – which hosted live performances by Marc Bolan, Slade, Mud, The Sweet, Status Quo, Mary Wells, Edwin Starr, 10,000 Maniacs, and Vinegar Joe, as well as local acts.

Flats The centre included eight flats. While initially popular with some residents, the flats suffered from poorly constructed roofs and leaking walls. Only one tenant was left by March 1979 and the flats were later boarded up.

Demolition

During the 1980s, the centre became increasingly seedy and the nightclub was developed into a casino. The shops slowly left, with the last ones departing in March 2002. The centre's car park was also the scene of many suicide attempts, being amongst the tallest publicly accessible buildings on the south coast. For this reason, a plaque offering support from The Samaritans was positioned at this infamous point. Numerous attempts to get the building listed as amongst the best examples of Brutalist architecture failed throughout the 1990s, and neglect, in addition to Portsmouth's wet coastal climate, caused the building to fall beyond the scope of easy repair. Structural steel within the concrete began to rust causing expansion of the concrete, and in some sections, small stalactites began to grow off ledges. Portsmouth City Council deliberated the demolition of the centre for many years; however, the uniquely designed car-parking block, which provided 400 parking spaces, was too useful for the city to destroy until 2004. The site is now occupied by a ground-level open-air car park. Opponents of demolition argued that the structure, while sadly undermaintained, was still salvageable with the work of ingenious designers and a long-term city plan. Essayist Jonathan Meades commented: "You don't go knocking down Stonehenge or Lincoln Cathedral. I think buildings like the Tricorn were as good as that. They were great monuments of an age." However, government and public opinion was that the building had decayed too far and had attracted such a bad reputation that the only option was to replace it. The Tricorn was the subject of such strength and diversity of public feeling that opinion boards were placed around its boarding for the public to write on.

Worked examples

Example 1 — a first encounter with Tricorn Centre

Start with the simplest possible case. Write down what Tricorn Centre 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 Tricorn Centre 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 Tricorn Centre 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 Tricorn Centre

In research
Tricorn Centre 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 Tricorn Centre 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
Tricorn Centre is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1966 establishments in England, 2002 disestablishments in England, Brutalist architecture in England, so understanding it makes those chapters shorter.
In everyday life
Look for Tricorn Centre 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.
