Saint-Omer Cathedral is a Roman Catholic former cathedral, a minor basilica. It was formerly the seat of the Bishop of Saint-Omer, but the see was not restored after the French Revolution, being instead absorbed into the Diocese of Arras under the Concordat of 1801. The church is still commonly referred to as the 'cathedral' however.
The cathedral is an excellent example of the flamboyant style of gothic architecture of the 13th, 14th and early 15th centuries. The substantial, square tower (15th-16th century) is reminiscent of perpendicular gothic towers in England, such was the cross-over of architectural styles in the period. A 12th century octagonal tower also survives from an earlier building. Despite the length it took to construct, the overall effect is remarkably harmonious and uniform, in part because of the use of the distinctive local white limestone.
The church is also well-known for its sculpture and furnishings. The highlight is the "Descent from the Cross" by Rubens, but it also has a working astrological clock from 1558, some stained glass from the 15th century, the tomb effigy of Saint Omer himself (13th century) and interestingly, a statue of God from Therouanne, dated to around the 13th century: his strange proportions reflect the original intention to place it 60ft from the ground. Both south and west doors have interesting decorative sculptures, including a 13th century Doom on the south door.
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.
