The predecessor of the current chateau in Líšno used to be the Castle of Léštno, established probably after 1367 when the sons of Ondřej of Dubá divided their inheritance. Beneš of Dubá who was given this section of land built his seat in a suitable spot protected by swamps and ponds. His son Václav of Dubá accompanied Master Jan Hus to Constance, however he did not join the Hussites and therefore the Taborites besieged his castle in 1420. In 1467, in the fights of Zelenohorská jednota against Jiří of Poděbrady, Léštno was conquered and reduced to rubble. At that time the estate belonged to the Šternberk family who later reconstructed and fortified the castle. The castle was reconstructed in 1478 and 1536. During the 30-years War, when the whole area suffered due to the consequences of the war, the local estate was ravaged too. The dishevelled castle became dilapidated and the ever changing owners had very little interest in its destiny. Between 1873 and 1884 Čeněk Daněk, a rich Prague industrialist, renovated the castle from scratch and converted it into a luxurious home, however maintained some Gothic and Renaissance Style parts. Thus the current chateau of Líšno, surrounded by a decorative park, was created. It has been built as a three winged two storey chateau around an oblong courtyard closed with a wall with a gate in the fourth side. The middle wing has a ground floor arcade. The courtyard facade of the left wing is decorated with statues of knights and a coat of arms. There is a prismatic tower in the corner of the right wing. In the park, there are pavilions, a statue of St. Florian, vases, a pool, a pond with a meadow and woodland areas. The chateau was acquired by the state in 1945. http://tourist.posazavi.com/

Původně zde stával hrad Léštno, který založil asi 1367 syn Ondřeje z Dubé, Beneš. Jeho syn, Václav z Dubé, zpočátku vystupoval proti husitům. Proto byl hrad v roce 1420 obléhán husitským vojskem. Když husité po dosaženém příměří odtáhli, držel Václav hrad až do roku 1424. Poté, až do roku 1443, tu sídlil Jan Sádlo ze Smilkova. V polovině 15. století získává hrad Zdeněk Konopišťský ze Šternberka, stoupenec Jiřího z Poděbrad. Zdeněk pomáhal Jiřímu proti Strakonické jednotě a roku 1450 dobyl se svými vojsky hrad Kostelec (dnes Zbořený Kostelec). Zdeněk ale v roce 1465 krále Jiřího zradil. Proto v roce 1467 královské vojsko oblehlo všechny Zdeňkovy hrady - Lišno, Konopiště a Český Šternberk. Hrad Lišno byl dobyt a Jiří z Poděbrad ustanovil novým pánem jednoho ze svých synů, Hynka z Münsterberka.
