Michalovice castle is located near the Jizera river, about 3 kilometres northwest of the town of Mladá Boleslav.
The ruins of the early Gothic Michalovice castle stands on the right bank of the Jizera river. It was built by members of the Markvartice family during the last quarter of the 13th century to replace an earlier manor house. It was left to decay already in the 15th century. In the 19th century the ruins of the castle were sacked by treasure hunters, and now only the look-out tower remains.
The robust cylindrical leaning tower is the reason the castle has often been called the tub of Michalovice ('Michalovická Putna').
References: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.
