01 ／ Shiramine Mausoleum

Defeated in the Hōgen Rebellion,he rests in what is said to be Shikoku's only imperial tomb.

In 1156, Retired Emperor Sutoku was exiled to Sanuki after the Hōgen Rebellion (保元の乱), and died in 1164 at age 46. His remains were cremated at Shiromine, which became his mausoleum. The Imperial Household Agency manages Shiramine no Misasagi, a square-mound tomb, and it is said to be the only imperial mausoleum in Shikoku. The neighboring Shiromine-ji (白峯寺) is temple No. 81 of the Shikoku pilgrimage.

02 ／ Kiyama Ancient Fortress

Around the Battle of Baekgang,stone walls rose on Mount Kiyama.

Believed to date from the late 7th century, amid tension with the Korean peninsula, this ancient mountain fortress spans from Sakaide into Hanzan, Marugame. Designated a National Historic Site in 1951, it still has stone ramparts, a water gate, and gate-post stones called Horoso-ishi and Manaita-ishi.
