 Behind the first, irregular court Cardinal d'Amboise constructed a range, the "Galerie des Cerfs" with the central triumphal gateway, the "Porte de Genes" (the "Genoa Gate"), which set apart a trapezoidal "cour d'honneur" surrounded with two-storey ranges, two facing one another with arcaded lower storeys.High pitched slate roofs were rhythmically pierced with dormers.A helical staircase tower stood in one corner.
