The castle was intentionally destroyed and the remains of the castle were almost completely dismantled. It is therefore not possible to recognize its development and its disposition is also indistinct. The castle hill is overgrown with vegetation, which covers the remains of fortifications and small remnants of masonry. The access road leading to the plateau between the upper castle and the rock with the transmitter, where the fort was separated from the upper castle by a neck ditch, is obvious. In the NE tip of the approximately pentagonal floor plan, a corner of the ground floor space, probably a prismatic tower, is preserved. The perimeter of the castle is delimited by carved rocks and rubble of crumbling walls and in the south there is another fragment of a matching wall.In the middle of the slightly rising surface of the courtyard, a well was documented, after which a depression remained. The jamming, modification of the plateau and the vertically parted face of the rock under the transmitter are probably the work of Kremnica miners.

Krásin Hill was inhabited as early as the Bronze Age. In 1208, the castle is not mentioned in the deed of the mayor of Nitra, but the territory of Sucza is mentioned for the first time when defining the boundaries of the property of the bishop of Nitra.

The guard castle in Krásin was probably built by the mayor of Trenčín, Bogomír, the son of Sebeslav of the Ludanický family, in the 13th century. The castle guarded the trade route and the border crossing from Hungary to Moravia. In the years 1267-1321, the castle was owned by the Čák family, most recently Matúš Čák. The first undoubted mention of the castle is a document from 1318, which mentions the castellan (castelanus de Zucchan) Dionysus called Levo. After the death of Matúš Čák, the castle was occupied by the royal troops of Karol Róbert and was in royal hands until 1393. After that, King Sigismund of Luxembourg founded it for his faithful and devoted warrior, Stibor of Stiborice.

In 1421, Sigismund donated Súča Castle, together with Bystrica, Vršatec, Starhrad, Strečno and Žilina, to his wife Barbora Celjská, who contributed to strengthening the castle fortifications, expanding and deepening the moat. The castellan was then Mikuláš Soboňa, who, however, became an ally of the Hussites, against whom the castle was to defend. After Sigismund's death in 1437, several owners changed in Súča. Albrecht of Habsburg confiscated his testine's property and donated it to his wife Elizabeth. Then the castle fell into the hands of Elizabeth's cousin Ulrich Celjsky.

Ulrich, Count of Záhorie and Ban of Slavonia, owned the castle and the estates of Súča until his violent death in 1456, when he was assassinated by friends of Ladislav Hunyadi. The castle then fell to the crown.

In 1475, Matej Korvín gave the castle together with Trenčín, to Duke Štefan Zápoľský, as a reward for his faithful services. Vladislav II. upon his accession to the throne in 1490, he confirmed the reserve property to Zápoľský and in February 1493 he donated the castles of Trenčín and Súča to him. Zápoľský was already the palatine of Hungary at that time.

The special history of Súča and the castle was the period of the Podmanický landowners, when after the defeat of Ján Zápoľský near Tokaj on September 25, 1527, King Ferdinand I., financially exhausted by long wars with the Turks, gave Súča Castle in 1527 with the villages to the bishop of Nitra Štefan Podmanický. His nephews Ján and Rafael Podmanický became heirs. Rumors of their robberies forced the monarch to transfer the lien of the Súča to the palatine Alexej Thurzo in 1534. However, the castle did not pass into its permanent ownership, because Ján Podmanický conquered Súča in 1536 by a sudden attack and Thurzo did not regain it even after a long siege.

The Podmanický brothers experienced the greatest expansion around 1540, when they owned Bystrica, Súča, Košec, Budatín, Lednica, Hričov and Palota Castle, where the elder Ján lived. However, at the instigation of many complaints, the Hungarian Parliament in 1542 decided on their exile if they did not return the property to the original owners. Although the brothers took an oath of allegiance to Ferdinand I, in reality they did not rush to return the property. By changing the situation in Hungary, the council pardoned the brothers and King Ferdinand again accepted Raphael among his faithful. Ján Podmanický has died in the meantime.

The ownership of Súča Castle caused a lot of controversy at that time, as the castle was owned illegally by both brothers all the time. Rafael promised to hand over the castle with all its armaments and accessories by November 1549, if the king compensates him. However, the castle was taken over by a commission in 1549, in which, in addition to the chief mayor Ján Ostrožič, the governor was Pavol Baračkay, the chief collector of the thirties Tomáš Francisci and the captain of Trenčín Castle Krištof Görtschacker with 80 soldiers. The Commission described precisely the military potential, as well as all the food and items there.

The castle was damaged during the war and gradually fell into disrepair. There was no interest in its reconstruction. Shortly after Rafael's property was taken away, the fate of the castle in Krásin was also decided. In 1550, King Ferdinand I of Hungary and Czech ordered his military commander Mikuláš of Salm to demolish the castle. Probably for fear that it would be seized again by other resistance fighters. Rafael's marriage to Jana, the daughter of Adam of Lomnica, caused a turnaround in his actions and the thinking of a robber knight. However, he died in 1558 while preparing for an expedition against the Turks.

In 1582, Imrich Forgách received the Sučany estate, by this time the castle was mentioned already as a ruin. The destroyed castle served the locals as an easily accessible building material.

The rumor says...

Robbers lived in Súča. They were stealing as a law of robbery preached until the captain brought his beloved wife to the castle. Woman like a sting. Her modesty was foreign to her, so the thefts in the area began to multiply. One day, when there was too much steals, an army approached Súča. As soon as the bandits noticed the ranks lined up in the distance, they raced out of the castle. The last to gallop on the horse was the pretty captain girl. The girl's long hair fluttered in the wind like a comet's tail, and it ruined her. The mane caught the beauty by the branch of a bushy tree and she fell from the horse. The soldiers caught up with her and hung her on a fateful tree. It happened where one of the settlements of Horná Súča is still called Beautiful Oak.

The remains of the walls are freely accessible
