"Sheriff William Owen Smith planted an Indian banyan tree in the courtyard square in 1873 to memorialize the 50th anniversary of the first American Protestant mission in Lahaina. The banyan tree has become the largest banyan tree in Hawaii, and one of the largest banyan trees in the United States. Its extensive trunk and aerial root system now covers 0.66 acres (0.27 ha). The park is managed by the County of Maui and the Lahaina Restoration Foundation."
