Kolárovo Castle
A minor fort with a disputed origin and a frog castle nickname.
Kolárovo Castle, originally called Fort Gúta, stood near the town of Gúta (now Kolárovo) in present-day Slovakia. Its site has never been archaeologically excavated. Historically, the fort was less significant than the larger fortresses at Érsekújvár (modern Nové Zámky) and Komárom (modern Komárno).
The original 14th-century castle had two parallel wooden palisades reinforced with wicker, with mud and dirt packed between them for strength. A moat surrounded the castle for extra defense.
Tradition says Queen Mary of Hungary ordered the castle built around 1349 near the confluence of the Váh and Little Danube rivers to guard fords and trade routes. Since Mary was born in 1371 and crowned in 1382, the castle was likely built decades later or ordered by her predecessor, Louis I. The fort was repaired and renovated many times. In 1527, as Turkish occupation began, local captain Gregor Martonosi Pesthényi quickly repaired it against the approaching army of John Zápolya, who was backed by the Ottoman Empire. That year, Zápolya’s commander Gáspár Ráskay took the town and fort, but it soon returned to imperial Austrian control. Between 1584 and 1594, Italian army engineers strengthened the fort. When Gabriel Bethlen captured the fortress at Komárno, local Walloon and French soldiers fled from Gúta.
After the Ottoman army took nearby Érsekújvár in 1663, the Kingdom of Hungary (part of the Habsburg monarchy) decided to modernize the fort. In 1664, it was rebuilt as a Baroque-style star fort with four triangular bastions. Further modernization between 1662 and 1664, driven by fear of new Turkish attacks, added stone accommodation houses and stone stores for gunpowder and guns. At that time, 130 mercenaries served under commander Matej Fröhwirtha. In spring 1707, during the Rákóczi uprising, Count Guido Starhemberg carried out fortifications worth 6,090 forints with army engineer Fischer. Kuruc general János Bottyán camped near the town four times. On 12 July 1708, he captured the fort with heavy artillery and took the mercenaries prisoner. After the fighting, the fort was destroyed, and the kuruc soldiers left saying, “Let it be the residence of frogs since now.” Though later repaired, it kept the nickname Békavár (Frog Castle). General Heister later stationed a Danish garrison there.

Lore & Background
Between 1662 and 1664, fearing new Turkish attacks, the fortress was modernized again, with stone accommodation houses and stores for gunpowder and guns, garrisoned by 130 mercenaries under Matej Fröhwirtha. In spring 1707 during the Rákóczi uprising, Count Guido Starhemberg performed fortifications worth 6090 forints. On 12 July 1708, kuruc general János Bottyán conquered the fortress with heavy artillery, captured the mercenaries, and destroyed it; kuruc soldiers retreated saying 'Let it be the residence of frogs since now,' giving it the defamatory name Békavár (Frog castle). A Danish garrison was later stationed there by General Heister. In the 1840s, the fortress had no importance, used only once by General Artúr Görgei's army for rest after a lost battle.
Reader's Guide
Kolárovo Castle (Fort Gúta) is a minor historical fortification whose significance lies more in its varied and often disputed history than in any major military role. Its construction date and patron are uncertain, reflecting the challenges of medieval record-keeping. The fort's evolution from a simple palisaded castle to a Baroque star fort illustrates changing defensive technologies and the pressures of Ottoman expansion. Its capture by kuruc forces in 1708 and the subsequent nickname 'Frog Castle' provide a colorful anecdote of the Rákóczi uprising. The fort's lack of archaeological excavation leaves many questions unanswered, making it a site of potential future research. Its legacy is that of a secondary stronghold that nonetheless witnessed key episodes in Hungarian and Habsburg history, from the Turkish wars to the 1848 revolution, though it never achieved the prominence of nearby fortresses like Érsekújvár or Komárom.
