Trenčín Castle was built on the site of an older settlement that existed here from the Bronze Age through the Celts and Germans to the Slavic settlement. At the time of the establishment of the Hungarian state, the older Great Moravian fortified settlement became a county royal castle. The oldest stone building of the castle is a pre-Romanesque rotunda, probably from the Great Moravian period. At the end of the 11th century, a stone refuge tower (donjon, bergfrid) was built, after 1270 it was added and expanded with a Gothic brick cladding. With its conical convergence towards the top, it forms a unique element of castle architecture in Slovakia. It is the center of the castle acropolis and the most distinctive visual dominant of the city panorama. Individual castle palaces were built in its immediate vicinity. Their construction was related to the expansion of the castle’s function from primarily defensive to administrative, administrative and residential. The oldest palace was probably Matthew’s Palace from the beginning of the 14th century, of which, however, only one wall has been preserved, which today forms part of Barbora’s Palace. It was the seat of Matúš Čák Trenčianský (around 1260 – 1321), who made it his residence castle and the center of extensive estates, the so-called “Matthew’s Land” or Terra Mathei. This, at that time the most powerful Hungarian magnate, controlled almost the whole of today’s Slovakia and a significant part of Transdanubia. He owned almost 50 castles and several counties. He not only seized the property of his weaker aristocratic opponents, but also plundered the royal dominion. He did not spare church property either, which even twice earned him a church curse and the declaration of an interdict (prohibition of the administration of the sacraments) over his property. He is said to have minted his own coins in Trenčín , but none have been found. And so it is probably just a slander of his many enemies. Matthew’s death on March 18, 1321 not only meant the immediate disintegration of his “kingdom”, but became the basis of several legends and legends. Since no one ever found his grave, it became a popular destination for various romantics, adventurers, treasure hunters and serious historians. Legend has it that he was buried in a tin, silver and gold chest with huge treasures. However, it is somewhat suspiciously reminiscent of the legend of the death of the “Scourge of God”, the Hun king Attila. Trenčín Castle returned to the property of the Hungarian crown, i.e. King Charles.
The Gothic Louis Palace, the construction of which is attributed to the son of Karol Róbert Louis, also called the Holy or the Great, is reminiscent of the Anjuv period. The Trenčín Museum has prepared an exhibition of cold and firearms from the 13th to 19th centuries. We can find Gothic swords, sabers and clubs, or parts of late Gothic armour. Firearms include flint and percussion rifles and pistols, Prussian “needle guns”, richly decorated hunting rifles, as well as oriental weapons, yatagans, handjars and rifles.
The Gothic style with early Renaissance elements is also represented by Barbora’s Palace, which is said to have been built by Emperor Sigismund of Luxembourg for his second wife Barbora of Cell, at a time when the Trenčín estate belonged to Barbora’s dowry estates. The last, third palace at Trenčín Castle is the Zápoľský Palace, dating from the period of the dominion of the powerful Zápoľský family. It was probably built in the late Gothic style with elements of the early Renaissance by Štefan Zápoľský and his wife Hedwig, Princess of Tešín. Their son, the later Hungarian king Ján Zápoľský, lost the castle thanks to the Habsburg duke Johan Katzianer, whose troops besieged the castle in May 1528. After cannon shelling, which caused the explosion of the castle powder house and after it was obvious that Zápoľský could not help the castle, the garrison surrendered the castle on June 15 for personal safety and honorable departure . In the Zápoľský Palace, the Trenčín Museum placed a set of paintings from the Ilešházi collection, which is one of the most comprehensive aristocratic art collections in Slovakia. However, its artistic and historical significance goes beyond the borders of Slovakia and belongs to the cultural wealth of united Europe. Almost a hundred exhibited paintings represent several artistic styles and genres, from the late Renaissance, through Baroque to Romanticism. In addition to an important portrait component, it includes landscape work, still lifes, hunting motifs, marinas, battles and sacral paintings. Names such as J. K. Hoffstedtter, Daniel Schmidelli, Jean Luicxs and Daniel Michorn belong to the most important personalities of painting of their time.
The Zápoľsk family decided to solve the problem of the only vulnerable point of the castle, the long saddle of Brezina connected to the castle rock from the south side. All attacks on the castle fortifications were and could only be led from here. The new Southern Fortification cut the saddle with two dry ditches and three fortification zones with loopholes and pitch noses. At that time, the already obsolete Gothic system was strengthened by two artillery bastions of the new Renaissance roundel type, Jeremiah’s Bastion and the Mill Tower, located in the central axis of the defense. From an architectural point of view, it is a unique fortification system, unique in Central Europe. No less unique building from this period is the building of the barracks for the castle garrison, next to the second castle gate. The reign of Štefan Zápoľský also gave birth to one of the oldest and most beautiful Slovak legends about the Well of Love.
However, Trenčín Castle did not only experience war and violence. It hosted crowned heads from almost all over Europe within its walls. Its convenient location near the borders of the three kingdoms predestined it as a place for diplomatic meetings and meetings. On August 24, 1335, the Polish King Casimir, the Hungarian King Charles Robert with his son Louis and the Czech King John of Luxembourg, accompanied by his son Charles, met at Trenčín Castle for peace negotiations. The Czech monarch renounced the title of King of Poland, for which he kept the Piast Duchy in Silesia. In 1362, peace negotiations between Louis the Great and the Roman Emperor Charles IV took place here again. Both rulers resolved their disputes over Aquilea here. Peace was concluded two years later. On this occasion, both monarchs, as was customary, exchanged lavish gifts. King Louis received a gilded Gothic monstrance from Charles , which is still part of the temple treasure of the Parish Church in Trenčín, and he himself presented the emperor with a crystal kettle, which is now stored in the Cathedral Church of St. Vitus in Prague. Emperor Sigismund of Luxembourg and later King Matthias Corvinus used Trenčín Castle in a similar way. However, the walls of Trenčín Castle also welcomed guests who visited it for a more joyful purpose. In 1461, the already mentioned King Matthias with his mother Elisabeth expected his fiancée, daughter George of Poděbrady, Czech princess Catherine (Kunhuta), and in 1512 the engagement of the daughter of Štefan Zápoľský with the Polish king Sigismund took place at the castle. (The diplomatic traditions of Trenčín Castle have not been forgotten. On 24-25 May 2002, a summit of prime ministers and ministers of foreign affairs of the Visegrad Four and Benelux countries was held here, and in 2004 a visit of participants of the parliamentary meeting of NATO countries took place at the castle.)
From the 15th century, the originally royal castle gradually fell into the hands of aristocratic owners, either by lien or purchase. Among the most important were the Thurzo family, the Forgáč family, the Tyrolean count Pirrhus of Arc, the royal tavern owner Juraj Zrínsky, Ladislav Popel Jr. of Lobkovice, the Rákoci family and several others had an ownership share here.
In the middle of the 15th century, the Hungarian palatine Alexius Thurzo had the Renaissance Cannon Bastion built in the northern corner of the lower courtyard, which protected the Upper “Water” City Gate with a bridge with its cannons. Today it serves as an exhibition hall of the Trenčín Museum.
From 1548, repairs were carried out at the same time as the castle, damaged by Katzianer’s troops. Count Imrich Forgáč invited Italian and German stonemasons and masons to the castle to repair and improve it. The work took place in the years 1583 – 92 and resulted in, for example, the construction of the barbican of the First Gate with two cylindrical bastions, or the visual unification of the castle palaces with Renaissance arched attics.
In 1594, Štefan Ilešházi obtained a lien on Trenčín Castle and bought it in 1600. He thus laid the foundation for the power and glory of one of the most powerful magnate families of Hungary, the hereditary counties of the Trenčín and Liptov counties. Although the Ilešházi family did not build any more important buildings in the castle, they completed the reconstruction, which was started by Forgáč. In the 17th and 18th centuries, the designed modifications in the spirit of the Baroque fortification system were no longer implemented for the most part.
The invasion of the Turks on Považie in 1663 initiated the last strengthening of the castle’s defense. The southern fortification was reinforced with a Baroque star bastion element, completed in 1673, but it has not been preserved. Subsequently, the emperor placed his own garrison in the castle in the strength of about 400 men. As a result, the Ilešházi family finally moved to their new castle in Dubnica nad Váhom. On this occasion, in 1678, they ordered their provisor to write down a detailed inventory of the castle furniture and supplies. This document, written in Slovak, informs us in detail not only about the equipment of the castle and the equipment of the kitchen, craft workshops, but also about the state of food, armour and armament stocks. It also provides the first historical information about the Ilešházi picture collection and the documentary archive.
At the end of the 18th century, Trenčín Castle definitively lost its military significance and subsequently, in 1783, the imperial military garrison left . A huge fire on June 11, 1790, which almost destroyed the city, also affected the castle in a devastating way . The last member of the famous family, Stephen II. Ilešházi sold the Trenčín estate and the castle in 1834 to the nobilized banker Count Georg Sin. The last owner, Iphigenia De Castris D ́Harcourt, donated the castle to the city of Trenčín in 1905.
The first repairs of the dilapidated ruins began in 1912, but systematic reconstruction has been underway since 1956 to this day.
Trenčín Castle saw under its walls the enemy armies of the Czech and Polish kings, the Tatar hordes, Bočkai’s and Bethlen’s outlaws, the imperial landsknechts, the Janissaries and bashibozuks of the Turkish sultan, the Tatars of the Crimean khan, the companies of the duke of Saxony, the Kurucs and the Labans. However, it was never conquered by direct attack.
