The Achi monastery is a single-nave hall church, built of hewn stone. Constructed at the end of the 13th century or in the early 14th, it was later reroofed, renovated and surrounded by a defensive wall. The whole interior is frescoed. Some murals, stylistically dated to the late 13th century and betraying affinities with the Palaeologan art, are iconographic rarities, such as those depicting the life of Saint George.
The Achi monastery was favored by the Princes of Guria, especially Simon I Gurieli and Kaikhosro I Gurieli in the 17th century. Both made significant donations to the church and Kaikhosro made it a metochion of the bishopric see of Shemokmedi. The abbotship of Achi was then hereditary in the Salukvadze-Taqaishvili family. The church housed a gilded silver cross with a Georgian inscription mentioning the queen Tamar, which was discovered by Ekvtime Taqaishvili. The item was preserved in the Salukvadze family during the Soviet period and returned to the Achi church in 2015.

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.
