The front of the Duke's Mansion resembles several "mountain" shapes that protruded into Tahrir Square, and three courtyards are surrounded in the middle. On the far right Bar Courtyard (La Cour de Bar), there is Barta (La Tour de Bar). After becoming Duke of Burgundy in 1363, daring Philip quickly set about renovating the former residence of Duke Capé. In 1365, he built a new tower with a fireplace in the Great Hall, on the ground floor of the former Church of Saint-Chabel. The name Balta is derived from the Anjon King Barr, who was imprisoned here from 1431 to 1437. The stone carvings above the top staircase (L'escalier de Bellegarde) on the edge of Balta are very beautiful and a good place for photography. There was a exactly the same staircase on the opposite side of the Duke's House Logis, which has now disappeared. Looking at the empty place in the middle of the door, Think of the various cut-out wood carvings seen in houses across the Jiangnan. Revolutions are similar everywhere. On the south side of Bar Courtyard is the kitchen of the former Duke's Mansion (Les cuisines ducales), rebuilt in 1433 during the good man Philippe. The 12-meter-long hall is supported by eight pillars to lift the central vault. The pointy vault has a hole in the center to emit the fume from cooking. The three-sided wall is a huge barbecue fireplace. Standing in front of the fireplace, I was struck by its size: each of the six fireplaces was said to be able to barbecue a whole cow. Up to thirty chefs were busy here, and you can imagine the scene of the Duke's house bells ringing. Four large windows under the high pointed arch on the eastern wall of the kitchen brought light to the kitchen. Outside the kitchen, there was once a place of the same size for bread and pastries (1853, to be demolished for the new gallery), which enclosed a small courtyard with a well in the middle of which was a water-filled well, and today only the empty kitchen and the well can be seen.
