The small town Rabí is well-known due to the large castle. It is situated about 10 km north-east of the town Sušice, 487 m a.s.l.

Around 1499 this small town arose from the original settlement around the castle, which was built at the beginning of the 14th century. The town was fortified and it obtained a lot of rights and privileges.

The oldest building in the town is the Gothic Church of the Most Holy Trinity, built in 1498 in the place of the original church, which was founded near the castle after 1300. The new church was used as a castle chapel and its rostrum was accessible directly from the gallery on the castle walls. The church was renewed in 1907. Its nave is arched with the tracery ribbed vault and it has the pentagonal presbytery.
The Pseudo-Gothic town hall from the 19th century stands in the square. A few houses, which were built in the style of the so-called rural South-Bohemian Baroque in the 19th century, can be seen in the square as well.
The remains of the town gate, which was a part of the fortification of the town, can be found on the upper side of the square.

The so-called Žižka's Pear Tree was traditionally planted under Líšeň hill (west of the castle) in the place, where the Hussite leader Jan Žižka lost the second eye - according to the legend - during the conquering of the castle.
The old Jewish cemetery can be found below the castle on the outskirts of the town.
The small Neo-Gothic waterworks was built in the 1930's not far from the town in the direction of the village Budětice.
