Mechelen town hall on the Grote Markt consists of two parts: the cloth hall with unfinished belfry and the Palace of the Great Council. The cloth trade went into decline in the 14th century and there wasn't the money to complete the building. For two hundred years the belfry was no more than a shell, until it was eventually provided with a temporary roof in the 16th century. The belfry is now a UNESCO world heritage site. On the right of the belfry you can see the oldest part of the town hall, the remains of the earlier cloth hall. On the left is the Palace of the Great Council. The Great Council never actually met here, because this wing was only completed in the twentieth century in accordance with the original sixteenth-century plans of the then leading architect Rombout Keldermans. The interior of the Town Hall is well worth seeing.
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.
