The greystone church of Valö was built in the late 1300s and renovated in the next century. This is a fascinating church to visit, since it has scarcely been altered structurally since the Middle Ages, and contains much interesting inventory from before the Reformation. This includes a processional crucifix from the 15th century and several medieval sculptures. There is also a fine medieval triptych, unusual for a church so small. During a restoration many fine sixteenth century frescoes were uncovered and have since been restored.
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.
