Château Saint-Maire ('Saint-Maire Castle') was built from 1397 to 1425 by the Bishops of Lausanne to serve as their fortified residence. Begun under Guillaume of Menthonay, it was completed under his successor, Guillaume of Challant, and named after Saint Marius, the first Bishop of Lausanne. It served as the bishop's residence until 1536, when Bern captured Lausanne and secularized the bishopric (the bishop, Sébastien of Montfalcon, escaped through a hidden stairwell). The Bernese installed a bailiff in the château and used it as an armory. Upon the creation of the canton of Vaud in 1803, it became seat of the cantonal government, a role it has retained.
The château was built as a single massive rectangular block, as was common at the time, with brick for the upper portion and sandstone for the lower portion. It originally had Ghibelline merlons, which gave it a somewhat Italian appearance, but due to the wet climate, the roof was extended and the merlons filled, probably in the 16th century. The windows that form a row just below the eaves fill the gaps between the merlons, and the arches above the windows fill the v-shaped openings in the Ghibelline style of merlon.
In 1789, the Bernese built an annex on the west side of the castle, through which it is now entered. A tower that formerly stood next to the château was demolished in 1890, and around the same time, a statue of Abraham Davelwas installed against the front wall.
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.
