There was originally a Roman castellum (Castellum Laurum) in Woerden, as part of the limes of the Roman Empire and thus part of the defense lines of the northern border of the Roman Empire. The first castellum was built in the 40s AD, and was destroyed in 69 AD during the Batavian rebellion. In 70 AD the castellum was rebuilt, and the Romans remained until 402 AD, with an interruption lasting from about 275-300 AD. The Castellum was located at the present site of the medieval Petruschurch and surrounding church yard. During construction work on a new underground parking facility in the city center of Woerden, the remains of numerous old Roman buildings and a Roman cargo ship were found.
The current castle was built in around 1160 by bishop Godfrey van Rhenen. Due to its strategic location on the border between the County of Holland and the Bishopric of Utrecht, various wars have been fought in and around Woerden. In 1410 John III, Duke of Bavaria-Straubing reconstructed the castle.
Until the 19th century the castle was used as a prison. There's even a pit prison in the northwest tower, which was used for unruly prisoners. In the 20th century the castle was part of military barracks and used for storage of all kinds of goods but poorly maintained. This caused severe decay. Today it is restored as a restaurant.
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.
