Musée de l’Annonciade is one of the oldest modern art galleries in France. This 16th-century former chapel in Place Grammont contains some dross but also cracking stuff from artists connected with Provence in general and St Tropez in particular. Look out for Matisse, Utrillo, Seurat and Dufy. You should also have a look at the pointillist works of Signac, the first artist into St Tropez in the late 19th century.
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.
