The imposing fortress of the Seyssel d'Aix Castle overlooks the town of Sommariva del Bosco. The western part of the complex, facing the plain, is an 18th-century wing resembling a noble villa, while from the original circular fortress with its nine towers, only the northern side remains (visible from Via Carlo Alberto, known as the podium road, leading from the town hall to the old upper district). This part includes three massive cylindrical towers from the 13th century and a large octagonal tower, also from the 1200s, framed by a loggia designed by Benedetto Alfieri.
Beneath the roots of the ancient park's trees, surrounding the castle today, lie the ruins of the oldest part of the village, gradually dismantled for strategic purposes over the centuries.
The original building, possibly dating back before the year 1000 and certainly standing by 1153, makes it one of the oldest and best-preserved structures in the Roero region.
Throughout its history — marked by sieges, epic battles, betrayals, oaths, torture, and executions — the castle has been a coveted prize for local noble families due to its unique strategic position: the Acaja, the Roero, and the Savoy families all fought over it, until the Savoys ceded it in 1733 to the Seyssel d'Aix family, who still own and live in the castle today.
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.
