In 1829, at the suggestion of Queen Kaʻahumanu (with likely support from Hoapili), Boki and Liliha gave the lands of Ka Punahou to Hiram and Sybil Bingham, leaders of the first missionary group to Hawaiʻi. The Binghams built their home there; Kaʻahumanu wanted to be close to them and built hers nearby (the Binghams later built an adobe house, with thatched roof.) A memorial boulder near Old School Hall and the Library marks the location of the makai door of the Bingham home.
Roaming cattle became a nuisance. To protect the Bingham’s property and surrounding areas, in 1830, Queen Ka‘ahumanu ordered that a wall should be built from Punchbowl to Mōʻiliʻili. “The object of the structure was to keep cattle grazing on the plains from intruding upon the cultivated region towards the mountains.” “Kaahumanu’s wall came from ‘the reef’ (suggesting it was made of coral.” The thoroughfare which ran alongside the great wall, Stonewall street; it was also known as “Mānoa Valley Road; later, the route was renamed for the shipping magnate, Samuel G. Wilder (and continues to be known as Wilder Avenue.)
