Independence Gate

Independence Gate 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 Independence Gate rather than just read about it. In short: Independence Gate (Korean: 독립문; Hanja: 獨立門) or Dongnimmun is a memorial gate in Seoul, South Korea. It was built in January 1898.

Key takeaways

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

Reference excerpt

Independence Gate (Korean: 독립문; Hanja: 獨立門) or Dongnimmun is a memorial gate in Seoul, South Korea. It was built in January 1898. Its construction was planned by Philip Jaisohn, as a symbol of Korea's commitment to independence. It was designated as a Historic Site of South Korea in 1963, and relocated 70 metres (230 ft) northwest from the original location in 1979 for preservation. Dongnimmun measures 14.28 meters in height and 11.48 meters in width, and is made of approximately 1,850 pieces of granite.

History

Background

In early 1895, the Government of Joseon abandoned its long-standing diplomatic policy of sadae. Under sadae, Joseon was a tributary state of Qing China. To celebrate this change, the Government of Joseon demolished Yeongeunmun in February 1895, which they had built in 16th century as a symbolic gate for welcoming Chinese diplomats to the country. On April 17, 1895, the Joseon Government was formally released from China's sphere of influence with the conclusion of the Treaty of Shimonoseki between the Empire of Japan and the Qing dynasty at the end of the First Sino-Japanese War. Philip Jaisohn proposed the building a new gate near the former site of Yeongeunmun's ruins to symbolize the country's desire for freedom. This plan was approved by King Gojong, and the gate was named "Independence Gate".

Plan for construction To support construction of the gate, Soh created the Independence Club and published Korea's first modern newspaper named Tongnip sinmun. Regular citizens of Joseon donated to the construction of the gate via a public campaign run by the newspaper. Soh wrote the following in the English edition of that newspaper:

The croakers may croak and the pessimists may growl and the independence of Korea may be treated as a joke by those who can see nothing but the fact that His Majesty is still enjoying the hospitality of the Russian legation but they all argue from their fears and not from either present facts or future probabilities. Today we rejoice in the fact that the King has decided to erect upon the ruins of the arch outside the West Gate, a new one to be entitled Independence Arch. 독립문. We do not know as its inscription will be written in on-mun but we wish it might. For centuries the arch stood there as a constant insult to the autonomy of Korea, an autonomy which China always hastened to assert when called upon to stand responsible for any tremble in the peninsula but which site always denied when it was safe to do so. She denied it once too many times and now her "suzerainty" is where the old arch is, namely op-so. And now an arch is to be raised on the same spot to stand forever as a negation of Manchu dominance to show that Korea is once and for all cut off from the blighting influence of Chinese patronage; cut off, we hope, also from the system of fraud, corruption and trickery which today makes that most populous empire the laughing-stock of the world. This arch means independence not from China alone but from Japan from Russia and from all European powers.

Construction The design of Independence Gate was inspired by the design of the Arc de Triomphe in Paris. An unknown Swiss architect working for the German legation in Joseon created the blueprint for its construction. Its construction began in 1896, and finished in January 1898. The construction process was overseen by Korean engineer named Sim Ui-seok.

Subsequent history The Government of South Korea designated it as a historic site of South Korea in 1963. The gate was initially located north of the plinths of Yeongeunmun Gate, but was relocated 70 meters northwest from its original location due to the construction of Seongsan Road and its overpass. It is now located in Seodaemun Independence Park, easily accessible from Exit 4 or 5 of Dongnimmun Station on Seoul Subway Line 3.

Worked examples

Example 1 — a first encounter with Independence Gate

Start with the simplest possible case. Write down what Independence Gate 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 Independence Gate 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 Independence Gate 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 Independence Gate

In research: Independence Gate 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 Independence Gate 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: Independence Gate is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1890s establishments in Korea, Buildings and structures completed in 1898, Buildings and structures in Seodaemun District, so understanding it makes those chapters shorter.
In everyday life: Look for Independence Gate 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.
