The buildings of former Daoulas Abbey - a cloister and a 12th century font, an oratory and a monumental 16th century fountain, together with the 18th century conventual house - are an exceptional tribute to Breton art from the 10th century onwards. It was established by Guyomarch IV de Léon in 1173, but there has been at least a church since the 6th century. The former abbey was raided and looted by Vikings.
Daoulas Abbey was secularized in 1771-1792 and moved as a private property. The abbey has been renowned since 1986 for the quality and originality of its archaeological, historical or ethnological exhibitions organised in collaboration with some of the most known world wide museums. The abbey houses a superb medicinal garden with over 250 species. It is still structured and organised like most middle age/renaissance convent or monastery gardens.
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.
