The Basilica church of St. Ursula was is built upon the ancient ruins of a Roman cemetery. The church has an impressive reliquary created from the bones of the former occupants of the cemetery. It is one of the twelve Romanesque churches of Cologne and was designated a Minor Basilica in 1920. While the nave and crossing tower are Romanesque, the choir has been rebuilt in the Gothic style.
The Golden Chamber, or Goldene Kammer, of the church contains the alleged remains of St. Ursula and her 11,000 virgins who are said to have been killed by the Huns, possibly around the time of the Battle of the Catalaunian Plains. The original legend said only 11 virgins accompanied St. Ursula but the number grew over time, eventually to 11,000. The walls of the Golden Chamber are covered in bones arranged in designs and/or letters along with relic skulls. The exact number of people whose remains are in the Golden Chamber remains ambiguous but the number of skulls in the reliquary is greater than 11 and less than 11,000. These remains were found in 1106 in a mass grave and were assumed to be those of the legend of St. Ursula and the 11,000 virgins. Therefore, the church constructed the Golden Chamber to house the bones. The bones themselves are neatly arranged in 'zigzags and swirls and even in the shapes of Latin words.'

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.
