The buildings in the garden date back to the early 17th century. In 1625, the feudal lord of Takamatsu in Sanuki Province, Ikoma Takatoshi, began construction of Ritsurin, specifically the building of a garden around the South Pond using the beautiful greenery of Mt. Shiun ("Purple Cloud Mountain") as a backdrop. After Matsudaira Yorishige took control of the province, he continued the garden's construction. Work was completed by the Fifth Lord Yoritaka in 1745 after 100 years of improvements and extensions made by successive lords.
