Pill Priory is a Tironian house founded near Milford Haven in the late 12th century. It was founded as a daughter house of St Dogmaels Abbey near Cardigan, itself a priory of the Tironensian order of reformed Benedictine monks.
The community may always have been small; it was recorded as five monks in 1534 and four in 1536. In 1536 St Dogmaels Abbey and its daughters at Pill and Caldey were dissolved in the suppression of those monastic houses and fell to the crown.
The entire site remains in private hands. The free-standing remains of the priory church's chancel arch is now the most striking element of the site, and forms a garden feature, together with the remains of the south transept. The Pill Priory Cottage living quarters contain elements from the conventual buildings which were arranged around a more-or-less formalised cloister. The remains of all are constructed from Old Red Sandstone and Carboniferous Limestone, both from local sources.
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.
