The place was first mentioned in a letter of bishop Tobiáš of Bechyně from 1288–1289, when the town was part of the Prague episcopacy.
From the time Oldřich of Ústí came to power until 1547 Planá was a dependency of the newly established Hussite town of Tábor.
Then the town was bought by William of Rosenberg, who had a wooden bridge over the Lužnice river built.
The estate was inherited by Peter Vok of rosenberg, at the end of the 17th century it was taken over by the Sternbergs and later by the House of Lobkowicz, who had the original gothic church of Saint Wenceslaus rebuilt in 1666.
Another reconstruction took place in 1796.

After 1848, Planá became an independent municipality, which developed also thanks to the construction of the railway line (1869) and timber rafting, which ran here until 1946.
When the independent Czechoslovakia was formed, there was great cultural and industrial development – Sokol was founded, the cinema, library and new school were  built, and several companies were established, like Madeta dairy or Silon, nylon manufacturer.
