Torre Fiorenzana is a tower house built in the late 12th century for the local de Grono family. The first mention of the family is 1219. They appear again in local records in 1286 and 1288. The Canon Bernardinus of Grono and the Provost Heinrich appear to have been the last male members of the family. By 1314 it was owned by the powerful Lords of Sax-Misox and a branch of the family inhabited it. In the 14th century they were signing documents as de Saco de Grono and in the 15th century were de Saco de Fiorenzana. According to tradition, in 1406 the powerful leader of the family, Albert von Sax, was murdered at Fiorenzana.
In the 16th century the tower was locally owned. The coat of arms of the Three Leagues was painted on it at that time. Over the following centuries, it was inhabited by a number of local families and today remains privately owned. The exterior was studied and repaired in 1978.
The castle is located in the center of Grono village. It is a five-story, rectangular tower. The crow-stepped gables along the roof were added by the Lords of Sax-Misox in the 14th century. The original high entrance was located on the third floor and is still visible.

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.
