Tábor is a compact South Bohemian town with a sharper history than its size suggests. It was founded as a Hussite stronghold in the 15th century, and the old town still sits like a defensible knot above the Lužnice river: crooked lanes, fragments of wall, burgher houses, and a main square named for Jan Žižka.
The centre is small enough for a day but not thin. Žižka Square gives you the late-Gothic town hall, the church tower, and the monument to the undefeated Hussite commander. Beneath the same square, a section of the medieval underground tunnels is open through the Hussite Museum.
Walk out to Kotnov Tower and Bechyně Gate for the old fortification story and the view. If you want a softer finish, continue along the walls or down toward the river paths, where Tábor becomes less martial and more quietly Bohemian.
Tábor works well between Prague and South Bohemia, especially if you like towns where the history is not just a museum label. It is less spectacular than Český Krumlov, but it is easier to breathe in and has a strong identity of its own.
