Ussher Fort

Ussher Fort 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 Ussher Fort rather than just read about it. In short: Ussher Fort is a fort in Accra, Ghana. It was built by the Dutch in 1649 as Fort Crèvecœur, and is two days' march from Elmina and to the west of Accra on a rocky point between two lagoons.

Key takeaways

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

Reference excerpt

Ussher Fort is a fort in Accra, Ghana. It was built by the Dutch in 1649 as Fort Crèvecœur, and is two days' march from Elmina and to the west of Accra on a rocky point between two lagoons. It was one of three forts that Europeans built in the region during the middle of the 17th century. Fort Crèvecœur was part of the Dutch Gold Coast. The Anglo-Dutch Gold Coast Treaty (1867), which defined areas of influence on the Gold Coast, transferred it to the British in 1868. Because of its significance in the history of European colonial trade and exploitation in Africa, the fort was inscribed on the UNESCO World Heritage List in 1979 (along with several other castles and forts in Ghana).

History

Negotiations to build a Dutch fort on the site began in 1610, but did not bear fruit until much later. Fort Crèvecœur was built in 1642 as a simple factory and then enlarged in 1649 by the Dutch West India Company. It was named after Fort Crèvecœur in 's-Hertogenbosch in the Dutch Republic, which had played a crucial role in the Siege of 's-Hertogenbosch. One of the Dutch representatives, Henry Caerlof, developed good relations with the Dey of Fetu, who gave Caerlof permission to build Osu Castle in 1652 for the Swedish Africa company. Fort Crèvecœur and Fort James were neither as imposing nor as important from the political point of view as Elmina or Cape Coast Castle, built 150 kilometers further west. Still, they brought their owners significant revenue. At the end of 1781 Captain Thomas Shirley in the frigate HMS Leander, together with the sloop-of-war Alligator, sailed for the Dutch Gold Coast with a convoy consisting of a few merchant-vessels and transports. Britain was at war with the Dutch Republic and Shirley launched an unsuccessful attack on 17 February on the Dutch outpost at Elmina, which the Dutch repulsed four days later. Leander and Shirley then went on to capture the small Dutch forts at Mouri (Fort Nassau - 20 guns), Kormantine (Courmantyne or Fort Amsterdam - 32 guns), Apam (Fort Lijdzaamheid or Fort Patience - 22 guns), Senya Beraku (Berricoe, Berku, Fort Barracco or Fort Goede Hoop - 18 guns), and Accra (Fort Crèvecœur - 32 guns). Shirley garrisoned those facilities with personnel from Cape Coast Castle. Fort Crèvecoeur was completely destroyed, and rebuilt in 1839 by Dutch master of works Hubertus Varlet. Fort Crèvecœur, which lies to the east of the present port, became known in time as Ussher Fort in honour of the then Administrator of the Gold Coast, Herbert Taylor Ussher.

Currently

In all, Europeans built 27 forts on the coast of Ghana. The Dutch captured two forts from the Portuguese, and themselves built nine others. The British built ten, all before 1660. Today, only 11 of these forts are in good shape. Ussher Fort is currently being restored with funds from the European Commission and UNESCO. The purpose is to convert it to a museum and International Documentation Centre. The fort opening hours are 9:00am to 4:30pm from Mondays to Saturdays including public holidays. Chale Wote is hosted virtually in the premises of the fort.

Worked examples

Example 1 — a first encounter with Ussher Fort

Start with the simplest possible case. Write down what Ussher Fort 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 Ussher Fort 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 Ussher Fort 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 Ussher Fort

In research
Ussher Fort 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 Ussher Fort 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
Ussher Fort is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1649 establishments in the Dutch Empire, Buildings and structures completed in 1649, Castles in Ghana, so understanding it makes those chapters shorter.
In everyday life
Look for Ussher Fort 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.
