The Stoa of Attalos was a covered walkway or portico in the Agora of Athens. It was built by and named after King Attalos II of Pergamon, who ruled between 159 BC and 138 BC. The current building was reconstructed in 1952–1956 by American architects along with the Greek architect Ioannis Travlos and the Greek Civil Engineer Yeoryios Biris.
Typical of the Hellenistic age, the stoa was more elaborate and larger than the earlier buildings of ancient Athens. The stoa's dimensions are 115 by 20 metres and it is made of Pentelic marble and limestone. The building skillfully makes use of different architectural orders. The Doric order was used for the exterior colonnade on the ground floor with Ionic for the interior colonnade. This combination had been used in stoas since the Classical period and was by Hellenistic times quite common. On the first floor of the building, the exterior colonnade was Ionic and the interior Pergamene. Each story had two aisles and twenty-one rooms lining the western wall. The rooms of both stories were lighted and vented through doorways and small windows located on the back wall. There were stairways leading up to the second story at each end of the stoa.
The stoa is identified as a gift to the city of Athens for the education that Attalos received there. A dedicatory inscription engraved on the architrave states that it was built by Attalos II, who was ruler of Pergamon from 159 BC to 138 BC.
The stoa was in frequent use until it was destroyed by the Heruli in 267. The ruins became part of a fortification wall, which made it easily seen in modern times. In 1952-1956, the stoa was fully reconstructed and the Ancient Agora Museum was created by the American School of Classical Studies at Athens, with funding donated by the Rockefeller family.
The Stoa of Attalos houses the Museum of the Ancient Agora. Its exhibits are mostly connected with the Athenian democracy. The collection of the museum includes clay, bronze and glass objects, sculptures, coins and inscriptions from the 7th to the 5th century BC, as well as pottery of the Byzantine period and the Turkish conquest.
References:The Château de Chantilly comprises two attached buildings: the Petit Château built around 1560 for Anne de Montmorency, and the Grand Château, which was destroyed during the French Revolution and rebuilt in the 1870s. Owned by the Institut de France, the château houses the Musée Condé. It is one of the finest art galleries in France and is open to the public.
The estate"s connection with the Montmorency family began in 1484. The first mansion (now replaced by the Grand Château) was built in 1528–1531 for the Constable Anne de Montmorency by Pierre Chambiges. The Petit Château was also built for him, around 1560, probably by Jean Bullant. In 1632, after the death of Henri II, it passed to the Grand Condé who inherited it through his mother, Charlotte Marguerite de Montmorency.
Several interesting pieces of history are associated with the château during the 17th century.
