The Church of San Pedro Apóstol is considered a National Historic-Artistic Monument in Vitoria from the 13th-14th centuries. The temple was attached to the western wall of the medieval town, which is why the walls on the west are very thick. In the central nave the walls form a tower which is visible from the outside of the temple.
Gothic façade dates from the 14th century, accessible from Calle Herrería. The entrance is the opposite way round in this church because the wall used to run along the bottom of the central nave.
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.
