The Church of St Martin was begun in the 12th century, although most of the current structure dates from the 13th century. The church is most notable for its extreme tilt, caused as a result of a landslide. This has led to many attempts to strengthen the church and prevent its collapse, through the use of massive tie beams and buttresses.
The church is in the Gothic style, and has a chancel, nave, south porch, and western tower. A round-headed north window dates to the 12th century, and the nave roof has been dated to the late 13th or early 14th century.
In the nave of the church stands a stone cross, sometimes referred to as a wayside cross or crucifix, dated to the 11th or 12th century. In the Middle Ages the cross, which bears a rare carving of Christ on the cross, would have stood in the churchyard to be venerated by pilgrims travelling through the Black Mountains, via Llanthony Abbey, to St David's Cathedral in Pembrokeshire.
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.
