The Old Town in Aarhus, Denmark (Den Gamle By), is an open-air town museum consisting of 75 historical buildings collected from 20 townships in all parts of the country. In 1914 the museum opened as the world's first open-air museum of its kind, concentrating on town culture rather than village culture, and to this day it remains one of just a few top rated Danish museums outside Copenhagen.
The museum buildings are organized into a small town of chiefly half-timbered structures originally erected between 1550 and the late 19th century in various parts of the country and later moved to Aarhus during the 20th century. In all there are some 27 rooms, chambers or kitchens, 34 workshops, 10 groceries or shops, 5 historical gardens, a post office, a customs office, a school and a theatre.
The town itself is the main attraction but most buildings are open for visitors; rooms are either decorated in the original historical style or organized into larger exhibits of which there are 5 regular with varying themes. There are several groceries, diners and workshops spread throughout the town with museum staff working in the roles of town figures i.e. merchant, blacksmith etc. adding to the illusion of a 'living' town.
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.
