The wooden castle was founded in the rocks by the Valečov family after 1300. Later, because the family belonged to Jan Žižka z Trocnov's followers, the castle was conquered and burned in 1439 by Jindřich z Vartenberka during the Hussite Wars. It was then gradually rebuilt with stones. The castle only remained there for a few years until the arrival of the Prague campaign in 1443-1444. Several years later, in 1472, Vaněk z Valečova lived there, serving as the chamberlain of royal cities during the reign of Jiří z Poděbrad. Then, the castle owners quickly changed, until the powerful Valdštejn family acquired it with the entire estate in the early 17th century. The nobility did not live there; it served as their administrative center and was reported as abandoned in 1652.
Even in the 19th century, some local poor people resided in some of the rock chambers. However, the inhabitants were eventually forcibly evicted by an order of the district governorship in Mnichovo Hradiště on October 5, 1892.
Since 1994, the castle has been owned by the municipality of Boseň, on whose territory it is located.
The castle was comprised of a dominant core on three sandstone ridges with two outer courtyards and an extensive fortified area with a large number of rock chambers, originally used as winter quarters for Hussite field armies. A series of chambers and an access tunnel to the summit plateau were carved into the rock blocks beneath the castle core. A wooden or half-timbered Old Palace stood on the middle block. The surviving New Palace had two bays and an oriel window on the courtyard side. During the 16th century, when two owners lived in the castle, both palaces were modified to have their own entrance from the courtyard.
Several smaller buildings stood near the castle building, inside the walls, with a larger one serving as a dining hall and lodging for women. Additionally, there were several dwellings carved into the rocks. Under the walls was a lower castle with a series of buildings and dozens of rock chambers.
The ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
