Along the way, there are piles of raccoon dog droppings, and you can see the old san-gumi (cornerstone) construction of the Honmaru (main enclosure) ruins. When you reach the Tenshudai, the view of the Harima Sea and the wind blowing up is superb. ●『National Historic Site Designation: Marugame Castle』 　『Marugame Castle, the Castle of Stone Walls』 　　《Concentric Flatland Mountain Castle》　Marugame City 【One of the Twelve Remaining Castle Towers】【Castle of Stone Walls】 A steep "Mikaeri-zaka" (Looking-Back Slope) of 150m from the Otemon (main gate).

"In the past, the castle walls directly faced the Seto Inland Sea, and seawater was drawn into all the outer moats, middle moats, and inner moats, allowing 【warships】 to enter and exit the castle directly. It is Japan's first full-scale 【Sea Castle】, also considering the operation of the navy." 　-Excerpt- Because the moats were connected to the sea, there were 【water gates】 to regulate the water level due to the ebb and flow of the tide, and black sea bream, sea bass, and mullet swim in the inner moat. 　　《Tai Gan Joju》 (Sea Bream Wish Fulfillment) - Feed cost: ¥100 ●『Takamatsu Castle Inner Moat Sightseeing: Japanese Boat Tamamaru』 　《Castle Boat Experience》 ●『Important Cultural Property: Hiunkaku』 　《Former Matsudaira Family Takamatsu Villa》　Former Sannomaru "It is a modern Japanese-style building built in the Taisho era.
