San Andrés church was built in the quarter of Ajates (a suburb of mediaeval origin in which the main trade was masonry) in the second quarter of the 12th century. It was made in Caleno granite (very typical of the Romanesque style in the town) and is set according to liturgical criteria with an upper end with three apses that correspond to the three naves in the interior; it does not have a transept nave. The protruding central apse is of particular interest thanks to the number of figures and capitals and the closed arches on the straight section of the upper end, which stand as a unique example of Romanesque capitals. The variety of icons on the interior and exterior capitals is the largest of all of Ávila's Romanesque buildings and is associated with the Masters of León. The central apse has two absidioles of a smaller size and a plainer composition.
The upper end is covered with decreasing stepped vaults: barrel vaults along the straight section and calotte vaults along the curved section. The southern absidiole has a lobulated arch used as the entrance and unparalleled in any other church in Ávila at the time.
The south front has a semi-circular window and the keystone of the semi-circular archivolt contains a Chi Rho which, fitted in the 13th century, is considered as the first of its kind in the town. The tower stands next to the western side, built onto the nave during or after the 14th century.
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.
