Dynge Castle, also Dyngehus as it was once called, was a Norwegian fortified castle in use from approximately 1250 and onwards towards the beginning of the 16th century, when it burnt down. Located in central Bohuslän, since then passed into Swedish possession, the castle was mentioned several times in Norwegian records. The site was excavated 1912-1913 by Wilhelm Berg, who had also excavated the contemporary and largely similar castle Ragnhildsholmen Castle during the 1880s, and Olsborg Castle. Since then, the site has had no closer examination by archaeologists.
The castle was in shape similar to a motte-and-bailey, with a stone keep surrounded by a small moat, standing on top of a cliff overlooking Gullmarsfjorden. The foundations of the central keep's walls remain clearly visible, as does the moat. It is one of few remaining medieval structures in Uddevalla Municipality, alongside Dragsmark Abbey and Bokenäs Old Church.
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.
