Santillana del Mar Collegiate Church has its origins in a monastery dating from 870. Tradition has it that it was home to the relics of Santa Juliana.
Over the course of the 11th century it was transformed into a collegiate church, although the building visible today dates from the 12th century. It has three naves, with dome, transept, three semi-circular apses and a tower. The transept and apses conserve their original barrel-vaulted ceilings. Special mention should be made of the sculptural decoration of the doorway, the capitals and the cloister. Inside you can see medieval tombs and Romanesque reliefs from the 11th and 12th centuries. The main altar has an embossed silver front dating from the 17th century. Beneath this is another, in Romanesque style. The altarpiece is the work of a master artist from Burgos, dating from the beginning of the 16th century. A late-Gothic predelle was subsequently added, along with the Baroque statue of Santa Juliana between two Solomonic columns. On the main doorway there is a Byzantine pantocrator and an atrium flanked by two lions.
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.
