All Saints' Church is a chapel located in the Prague Castle complex. The site of the church was originally consecrated in 1185 and a Romanesque building built; the oldest parts of the current building date to a structure constructed by Peter Parler in the 14th century.
Although originally free-standing, the church was badly damaged in an 1541 fire which engulfed the palace and church. Through subsequent successive rebuildings and enlargements, the church became physically integrated with the palace, specifically Vladislav Hall.
The church holds the tomb of St. Procopius and his life is depicted on paintings on the walls. Although accessible from Vladislav Hall, the church is generally only open to the public during religious services and concerts.
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.
