Reference excerpt

Vyborg Castle (Russian: Выборгский замок, romanized: Vyborgskiy zamok; Finnish: Viipurin linna; Swedish: Viborgs slott) is a fortress in Vyborg, Russia. It was built by the Swedes during the Middle Ages around which the town of Vyborg evolved. The castle became the stronghold of the Swedish realm in the Karelian region. Throughout the centuries, it was the first defense of the kingdom against the Russians. Its military and strategic status in the late Middle Ages was second only to the fortified capital Stockholm. Currently it serves as the site of Vyborg Regional Museum.

Overview

Vyborg Castle was one of the three major castles of Finland, the three being the castles of Turku (Åbo in Swedish) and Hämeenlinna (Tavastehus), and Vyborg (Viborg). It was built as the easternmost outpost of the medieval Kingdom of Sweden: it is located on the Karelian Isthmus, on a little islet in the innermost corner of the Gulf of Finland, in a tight strait which connects Zashchitnaya Bay to Vyborg Bay. It was originally constructed in the 1290s on the site of Karelian fortress after the Third Swedish Crusade to Finland. The town was originally located inside the outer fortifications of the castle, at the fortress island, but it had to be moved to its present location off of the island because of lack of space.

History

Early history Excavations in 1980s indicated that a Karelian fortress pre-dated the castle built by the Swedes in 1293. The oldest layers of occupation have been discovered in the so-called Smith's Courtyard. A man-made breastwork of sand with timber posts was found from this area. Also charred remains of buildings, which some were linked to the breastwork, were also found. Tjulenev suggests that the Karelian fort had a wooden tower. Tjulanev's several finds from the area include a bent sword which was dated to the period between 1130 and 1200.

Medieval history Construction of the next phase of the fortress started in 1293 by orders of Torkel Knutsson, Lord High Constable of Sweden, who in the 1290s made a supposed crusade against Karelia, the Third Swedish Crusade. The crusade was part of the ongoing Swedish–Novgorodian Wars, against the Russians of the Novgorod Republic. Knutsson chose the location of the new fortress to control the Bay of Vyborg, which was bordered by trading sites long used by the local population. From the bay, a navigable river passage goes inland, ultimately connecting the place with several districts, lakes, and, indirectly by portage, with rivers flowing into Lake Ladoga. In 1364, Albert III of Mecklenburg was proclaimed king of Sweden, and in accordance with the German model he began to divide the castle fiefs, which were immense in Finland, into smaller provinces. In some instances, these new, smaller provinces were given separate bailiffs' residences which have since disappeared; this was the case with the Linnavuori castle mound in Porvoo (Borgå) and the castle of Korsholm in Ostrobothnia, near the modern-day city of Vaasa which was founded later. Only earthworks remain at these sites, but in two places, still-extant though now ruined stone strongholds were built: Raseborg Castle, in western Uusimaa (west of Helsinki), and Kastelholm Castle, in Åland. The castle and the large surrounding fief became a virtually autonomous principality. Its governors were usually enfeoffed with the incomes of the county. The fief of Viborg became known as a margraviate. Its governors were generally from the most powerful families of the kingdom. They enjoyed large administrative powers at a significant distance from the capital. These realities made them practically independent rulers. The castle of Savonlinna, Olavinlinna (built in the 1470s), was usually subjugated to Viborg. Prominent men who held Viborg as their fief included Bo Jonsson (Grip), Christer Nilsson Vasa (1417–42), Karl Knutsson Bonde (1442–48, the future king), Eric Axelsson Tott (1457–81), Knut Posse (1495–97), Sten Sture the Elder (1497–99, between his regencies), Eric Bielke, and Count John of Hoya. Particularly in the 1440s and the late 15th century, the fortresses were further enlarged. The first mention of firearms in Finland relates to Viborg castle in 1429. During the Middle Ages the Russians repeatedly besieged the castle, most famously in 1495 during the Russo-Swedish War (1495–97) while Knut Posse was governor of the castle. The situation of the defenders looked hopeless, but they were saved by the Viborg blast on 30 November 1495 (St. Andrew's Day), a mysterious explosion which scared the Russians away after they believed they had seen a Saint Andrew's cross in the sky.

Modern history

In the 16th century, much was renovated and additions were made. In the 17th century, the castle was allowed to decay, as Russian danger was lessened and the border was further eastwards. Viborg was taken by the Russians in 1710, but passed back to Finnish hands in 1812 when all of Old Finland was attached to the autonomous Grand Duchy of Finland. The castle owes its present appearance to extensive restorations undertaken in the 1890s. The military of the Russian Empire used the castle until 1918 for housing administration. Viipuri belonged to the newly independent Republic of Finland between 1917–40 and again 1941–44. As a result of border changes in World War II it was annexed by the Soviet Union in 1944.

Architecture The main castle, located in the eastern part of the islet on its highest hill, has an irregular four-cornered layout, with the immense tower of St. Olav (Pyhän Olavin torni in Finnish) as its biggest section. It is 3–4 storeys tall, varying in places. Outer defensive works surround the main castle, following the islet's coastlines.

Worked examples

Example 1 — a first encounter with Vyborg Castle

Start with the simplest possible case. Write down what Vyborg Castle claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, 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 Vyborg Castle 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 Vyborg Castle 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 Vyborg Castle

In research: Vyborg Castle appears in science 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 Vyborg Castle 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: Vyborg Castle is common in secondary-school and first-year university syllabi. It links to neighbouring topics 13th-century establishments in Russia, Castles in Finland, Castles in Russia, so understanding it makes those chapters shorter.
In everyday life: Look for Vyborg Castle 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.
