Ostrý Kameň Castle: a ruined border fort in the Little Carpathians
Ostrý Kameň Castle (German Scharfenstein, Hungarian Éleskő) is a ruin on a steep spur of Záruby, the highest peak of the Little Carpathians, above the village of Buková in the Trnava region. Founded in the 13th century to guard the old Czech Road, it is today a quiet forest ruin with a rock-cut moat and fragments of bastions, a good target for a hike.
A fort named for its sharp rock guarded the trade road from Buda to Prague, until the road moved to Bratislava and the castle was left to trees, robbers' legends and rare plants.
The history of Ostrý Kameň Castle
Ostrý Kameň was built in the 13th century and appears in written records for the first time in 1273. It was a royal border fort on the western edge of the Kingdom of Hungary, and its special task was to protect the long-distance trade route running from Buda through western Slovakia into the Czech lands, known as the Czech Road, or Via Bohemica. The road crossed the Little Carpathians through the depression of Bukovská brázda, right below the castle. According to the German Wikipedia, the route was officially fixed around 1335–1336 by the Hungarian king Charles I and the Bohemian king John, and it avoided Vienna in order to weaken Austria. Hungarian kings protected it with a chain of border castles, and merchants were meant to travel freely and safely, without tolls on the road.
The original castle was a small fortress at the top of the rock ridge, protected by steep drops that gave it its name. An oblong residential building joined to a prismatic tower with the entrance gate formed its core, and a moat cut into the rock separated it from the rest of the ridge. A forecastle with outbuildings and a water cistern were added gradually. At first the castle was royal property, but in 1366 the king gave it to Nicholas of Seč, and in 1394 King Sigismund granted it to the well-known commander Stibor of Stiboríc. Later owners included the Thurzo and Forgách families and, from the 15th century, the counts of Svätý Jur and Pezinok. From the middle of the 15th century the castle was extended to the north-west.
At the turn of the 15th and 16th centuries the castle became the hereditary property of the brothers Imre and Márton Czobor, and by then it served less as a lookout than as the economic and defensive centre of a large estate. A massive new fortification was built in front of the moat, and as the Ottoman threat grew, a second forecastle with a circular corner bastion was added; more forecastles followed in the second half of the 16th century. The grounds held residential buildings, storerooms, a bakery, a forge and a chapel. When Gáspár Czobor died in 1539, leaving debts to the Bakič and Révay families, a bitter dispute over the castle began, complicated by marriages and by the money the Bakič family had invested in the building. It ended only in 1554 after the direct intervention of Emperor Charles V, and four years later the three families divided the estate.
The castle's decline began in the early 18th century. In 1704 a large battle of Rákóczi's insurgents took place near the castle, which was probably damaged in the fighting, and around the same time the Czech Road was rerouted through Bratislava, so the fort lost its purpose. Frequent lawsuits between the owners did not help. At the end of the 18th century the estate passed to the Pálffy family, who moved its seat to Moravský Svätý Ján, and with nobody interested in repairs the castle slowly became a ruin. Robbers were active along the neglected road, and one of the legendary figures was a man called Hrajnoha.
