Prinsenkasteel ('Prince Castle') was founded in the 14th century by the lords of Grimbergen. The present castle was built around 1500 on the foundations of the previous fortress. In 1686 the Count of Grimbergen, Philippe-François de Glymes, was given the title of Prince by Charles II of Spain. The castle then became a princely estate, hence its name. After being damaged during the War of the Austrian Succession, it was restored in 1745 and embellished in the 1770s.
From 1901 to 1933, Premonstratensians from the abbey of Sainte-Anne de Bonlieu-sur-Roubion, expelled from France following the expulsion of religious congregations, were welcomed in the castle.
The castle ruins were bought by the municipality of Grimbergen in 1947. In 1978, the municipality also acquired the annex building, now called the Guldendal, which was formerly used as a stable, a carriage house and service building.
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.
