Saint Waltrude Collegiate Church dates back to 1450, and the origin of the famous chapter of noble canonesses that seated for centuries inside this church. The chapter played an important part in the local history, all of the Canonesse were familymembers of important noble houses. Antoine-Joseph Fetis, titular organist, taught his eldest son François-Joseph the first steps of the practice of organ music.
Inside the church important graves can be found amongst them Antoine de Carondelet and Alice of Namur.
The exterior of the church is a fine example of Brabant Gothic architecture, parts are built by Matheus de Layens. However in the 17th century the works stopped and the building was never completely finished. The interior contains important artworks, including sculptures by Jacques du Broeucq and paintings by Peter Paul Rubens, Floris de Vriendt, Theodoor van Thulden, Otto Venius and Michiel Coxie.
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.
