Rabí is the largest castle (in terms of area) from all Czech castles. Its name might derive from the German word raben ('raven'), or it could be mangled Czech name vrab(č)í vrch ('sparrow's peak').
The first mention of Rábí Castle dates from 1380, although it is not known exactly when it was founded. It is likely that the Lords of Velhartice established it after 1300 to protect trade routes along the Otava and also to inspect gold-bearing deposits in it. They built a strong palace, ramparts and a keep. Subsequent owners, the Švihovský of Rýzmburk family, continued building work and built the outer ward and two square towers.
At the start of the Hussite rebellions, the Švihovský family searched for havens of supporters of the Catholic side in the district and for their treasures, at Rábí. In 1420–21, the Hussites conquered the castle twice, and legend has it that during the second siege an arrow fired from crossbow hit the trunk of a pear tree and a resulting splinter from the tree hit Jan Žižka in his only good eye. In 1479, the provincial governor Půta Švihovský of Rýzmberk became the owner of the estate and began with a thoughtful remodelling of the castle under the guidance of famous master Benedict Rejt. New living quarters and service buildings were constructed, the castle was enlarged and the fortifications heightened.
Rabí Castle was, from the very start, envisioned as a donjon-type castle. It was built in the form of three separate sections, constructed in tiers above each other. The ramparts were up to 6 metres wide, and had bastions, vallum fortifications and moats. However, building activity exhausted the Švihovský family's finances and the fortifications remained incomplete.
Many alchemical experiences took place during Půta's time as well; a German alchemist who failed to transform lead into gold was then imprisoned in the castle's massive prismatic tower.
The slowly deteriorating complex was completely devastated during the Thirty Years' War, when Mansfeld's soldiers went on the rampage. Emperor Ferdinand III ordered that the castle should have been destroyed after 1650. In the end it was saved, but on the condition that it was not to be repaired. In time it became a source of building material for local peasants.
The last owners, the Lamberk family (from 1708) donated the castle to the Horažďovice Society for the Preservation of Artistic, Cultural and Natural Monuments for a symbolic price of 1 Kč in 1920, and after 1945 it was taken by the Czechoslovak State.

The imposingly grown complex originated in 1120 as a motte, a small hilltop tower castle. After numerous changes of ownership, the castle was extended onto two islands, but it was not until the 14th century that it underwent significant alterations and extensions under the von Oer family. The estate experienced its heyday in the middle of the 18th century, when it covered an area of almost one square kilometre and consisted of five further outer castles in addition to the core castle, which were secured by ramparts and moats.
The well-maintained condition of the castle today is thanks to the late Wilfried Grewing, the former lord of the castle. The foundation named after him has been particularly committed to preserving the property since 2020.
