St Catharine's Church is a Grade I listed building, built between 1875 and 1882. The church was constructed in the Decorated Gothic style, and dressed with Forest of Dean sandstone. John Prichard, Llandaff's diocesan architect, who also worked on the restoration of Llandaff Cathedral, was heavily involved in the design project, although the building work was superintended by a local architect named John Jones. It replaced the older St Baglan's Church, a pre-Norman building that was largely destroyed by a fire in 1954.
The interior uses Quarella stone, Forest of Dean sandstone and 'Penarth' alabaster to create a polychromatic effect. The chancel is decorated with bands of marble and has a marble floor inlaid with Italian mosaic tiles. A brass memorial plaque commemorates Griffith Llewellyn and his wife Madelina (née Grenfell), both of whom are buried in the churchyard, close to the ruins of the original Saint Baglan's church.
Stained glass windows in the church include designs by William Morris (St Cecilia with Musical Angels) and Edward Burne-Jones (Crucifixion with the Virgin Mary and St John), as well as a Celtic Studios design installed in 1972.

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.
