The Cathedral of the Blessed Virgin Mary in Truro was built between 1880 and 1910 to a Gothic Revival design by John Loughborough Pearson. It is one of only three cathedrals in the United Kingdom featuring three spires.
Truro was the first Anglican cathedral to be built on a new site in England since Salisbury Cathedral in 1220. It was built on the site of the 16th-century parish church of St Mary the Virgin, a building in the Perpendicular style with a spire 39 m tall. The central tower was finished by 1905 and the building was completed with the opening of the two western towers in 1910.
Pearson's design combines the Early English style with certain French characteristics, chiefly spires and rose windows.
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.
