San Miguel Church is built in the Romanesque to Gothic transitional style, apparent in the combination of elements from both styles inside. The richly ornamental northern front is in the Romanesque style and is considered one of the best in Navarre. The most interesting elements are the reliefs on either side of the front, which represent scenes from the Resurrection and the struggle of the Archangel St. Michael. The interior houses a Gothic reredos painted on stucco. It serves as the grave of the marquis of Muruzábal and Eguía. Of note among the sculptures on the reredos is a 17th century San Crispín.
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.
