Hwaseong Fortress

Hwaseong Fortress 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 Hwaseong Fortress rather than just read about it. In short: Hwaseong Fortress or Suwon Hwaseong (Korean: 수원 화성) is a Korean fortress surrounding the centre of Suwon, the provincial capital of Gyeonggi Province, South Korea. It was built from 1794 to 1796 by King Jeongjo of Joseon to house and honor the remains of his biological father, Crown Prince Sado.

Key takeaways

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

Reference excerpt

Hwaseong Fortress or Suwon Hwaseong (Korean: 수원 화성) is a Korean fortress surrounding the centre of Suwon, the provincial capital of Gyeonggi Province, South Korea. It was built from 1794 to 1796 by King Jeongjo of Joseon to house and honor the remains of his biological father, Crown Prince Sado. Sado had been executed by being locked in a rice chest by his father, King Yeongjo. Located 30 kilometres (19 mi) south of Seoul and enclosing much of central Suwon, the fortress includes King Jeongjo's temporary palace. The fortress and enclosed palace were designated as a World Heritage Site by UNESCO in 1997. It comprises among many other features a perimeter wall, four main gates, and two sluicegates over the Suwoncheon, Suwon's main stream, which flows through the centre of the fortress.

Background King Jeongjo apparently built Hwaseong Fortress to prepare for a move of the capital from Seoul to Suwon. Suwon was purported to be strategically positioned to connect Seoul with the West Sea (Yellow Sea) and China. The king wanted to leave the factional strife of the court to carry out reforms and believed that Suwon had the potential to grow into a new and prosperous capital. To encourage growth, he ordered people to move to Suwon at considerable expense and exempted them from taxes for ten years. King Jeongjo also ordered public works, such as the building of educational facilities to better facilitate the city as a capital. Suwon Hwaseong Fortress was restored based on the Hwaseong Seongyeok Uigwe, a design drawing from 200 years ago. The Hwaseong Seongyeok Uigwe is a blueprint showing the appearance of Suwon Hwaseong Fortress, the tools used to build it, and the location of Suwon Hwaseong Fortress. Because Suwon Hwaseong Fortress was restored based on perfectly preserved blueprints, it was exceptionally successful in being registered as a World Cultural Heritage despite being a modern restored building.

Construction

Hwaseong Fortress was built over a two-and-a-half-year period, from 1794 to 1796 according to the designs of the architect Chŏng Yagyong, who would later become a renowned leader of the Silhak movement. Silhak, which means practical learning, encouraged the use of science and industry, and Chŏng incorporated fortress designs from Korea and China along with contemporary science into his plans. The use of brick as a building material for the fortress and employment of efficient pulleys and cranes were also due to the influence of Silhak. Construction of the fortress was also a response to the collapse of the Korean front line during the Imjin war. At the time, the dominant model for building fortresses in Korea was to make a simple wall for the city or town and a separate mountain fortress to which the people could evacuate in times of war. However, this fortress was built to include elements of a wall, defensive fortress, and town centre, the four main gates being used as the gates for the town. The arrow-launching platforms built along ramparts with crenellated parapets and battlements were defensive elements of the fortress while the wall also included secret gates for offensive actions. The fortress took 700,000 person-hours to build and cost the national treasury 870,000 nyang, the currency at the time, and 1500 sacks of rice to pay the workers. In the past, government work had been carried out by corvée labour, but in this case workers were paid by the government, another sign of Silhak influence.

Records of Hwaseong Fortress Construction

A white paper, Hwaseong Seongyeok Uigwe (Records of Hwaseong Fortress Construction), was published in 1801, shortly after the death of King Jeongjo. It has ten volumes and proved invaluable for the reconstruction effort in 1970 after the fortress had been severely damaged during the Korean War. The volumes were divided by subject, with the first covering the plans for building, including blueprints and a list of supervisors. The next six volumes detail the actual implementation of the construction, such as the royal orders and records of the wages of the workers. The final three volumes are supplements and detail the construction of the adjoining palace, Haenggung. Labour was allocated by speciality, dividing workers by trade, categorising them as foremen, stonemasons, labourers, and so on. The records also detail the quantities of different materials used. An abridged French translation was published in 1898 by Henry Chevalier, who was consul of France in Korea, while a full German translation with commentary is provided in a thesis by Doo Won Cho of the University of Bamberg.

Overview of structures

Wall The wall is 5.74 kilometres (3.57 mi) in length and varies between 4 and 6 metres (13–20 ft), originally enclosing 1.3 square kilometres (0.5 sq mi) of land. On flat terrain the wall was generally built higher than that on either of the two hills over which it passes, as higher walls were seen as less necessary along hilltops. The parapets are made of stone and brick, like most of the fortress, and were 1.2 metres (4 ft) in height. All parts are well-maintained, and the whole circuit can be walked easily.

The Four Main Gates The 1795 fortress had four gates: Janganmun (north gate), Hwaseomun (west), Paldalmun (south) and Changnyongmun (east). Janganmun and Paldalmun are the largest of the four main gates and resemble Seoul's Namdaemun in roof design, stone and woodwork. Indeed, Janganmun is the largest gate in Korea. Both the north and south gates are topped with two-storey wooden pavilions, while Hwaseomun's and Changyongmun's, those of the west and east gates respectively, have only one storey. The four main gates are encircled by miniature fortresses which were manned by guards. Meanwhile, Changyoungmun was greatly destroyed during the Korean War and it was restored in 1978.

The Modern Days Entries Nowadays, the intra muros Suwon requires large entries for the modern roads needed by visitors and inhabitants. These large roads were built during the period when the wall was down, and the 1975 reconstruction had no choice but to preserve these roads. For three of them, the rampart walk has been rebuilt as a bridge between two neighboring structures:

Worked examples

Example 1 — a first encounter with Hwaseong Fortress

Start with the simplest possible case. Write down what Hwaseong Fortress 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 Hwaseong Fortress 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 Hwaseong Fortress 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 Hwaseong Fortress

In research
Hwaseong Fortress 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 Hwaseong Fortress 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
Hwaseong Fortress is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1790s establishments in Korea, Architecture in Korea, Buildings and structures completed in 1796, so understanding it makes those chapters shorter.
In everyday life
Look for Hwaseong Fortress 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.
