The Jerez Cathedral is a beautiful building from the 17th century which combines Gothic, Baroque and Neoclassical styles and stands above the earlier Great Mosque of Jerez and the old Church of El Salvador.
The chapels of La Inmaculada, El Sagrario and Las Ánimas stand out inside, the latter dedicated to the famous Cristo de la Viga, from the 14th century.
The bell tower, which is outside, was possibly built over the minaret of the old mosque of Jerez de la Frontera.
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.
