Its Kuruwa (the walls of the castle and the regions surrounded by them) lies from the tip of the hill, which protrudes from Fukuchiyama basin, to the Honmaru (the core of the castle) linking the Ninomaru (second bailey), Hokimaru (third bailey), and Naikimaru (fourth bailey) forming a Renkaku style (連郭式) serial Kuruwa.
曲輪は、福知山盆地に突き出た丘陵地の先端から、本丸、二ノ丸、伯耆丸、内記丸と続く連郭式である。
