The Cathedral of the Immaculate Conception in Sligo was developed by Bishop Laurence Gillooly who had been appointed Bishop of Elphin in 1858. He decided that the diocese was now of a size and wealth that the time had come to replace St. John's Parish Chapel, which had been recognised as the diocesan pro-cathedral.
He engaged George Goldie, one of the foremost Catholic architects in England in the nineteenth century. The cathedral was opened for divine worship on 26 July 1874 by Cardinal Paul Cullen of Dublin.
Modelled on a Normano–Romano–Byzantine style, it is the only example of a Romanesque style cathedral built during the 19th century. Designed in the shape of a basilica, the church has a square, pyramid-capped tower, which reaches a height of 70 metres, and supporting turrets at the west end. The circular baptistery incorporated in the apse with its five lancet windows behind the high altar, was originally designed as a mortuary chapel.
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.
