The Tarxien Temples are an archaeological complex dating to approximately 3150 BC. The site was accepted as a UNESCO World Heritage Site in 1980 along with the other Megalithic temples on the island of Malta.
The Tarxien consist of three separate, but attached, temple structures. The main entrance is a reconstruction dating from 1956, when the whole site was restored. At the same time, many of the decorated slabs discovered on site were relocated indoors for protection at the Museum of Archaeology in Valletta. The first temple has been dated to approximately 3100 BC and is the most elaborately decorated of the temples of Malta. The middle temple dates to about 3000 BC, and is unique in that, unlike the rest of the Maltese temples, it has three pairs of apses instead of the usual two. The east temple is dated at around 3100 BC. The remains of another temple, smaller, and older, having been dated to 3250 BC, are visible further towards the east.
Of particular interest at the temple site is the rich and intricate stonework, which includes depictions of domestic animals carved in relief, altars, and screens decorated with spiral designs and other patterns. Demonstrative of the skill of the builders is a chamber set into the thickness of the wall between the South and Central temples and containing a relief showing a bull and a sow.
Excavation of the site reveals that it was used extensively for rituals, which probably involved animal sacrifice. Especially interesting is that Tarxien provides rare insight into how the megaliths were constructed: stone rollers were left outside the South temple. Additionally, evidence of cremation has been found at the center of the South temple, which is an indicator that the site was reused as a Bronze Age cremation cemetery.
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.
