The Hilltop Arboretum at Louisiana State University (14 acres) is an arboretum owned by the Louisiana State University.[1] It is located at 11855 Highland Road, Baton Rouge, Louisiana, and open to the public free of charge during daylight hours seven days a week.
The arboretum was developed by Mr. and Mrs. Emory Smith, starting in 1929, and donated to the university in 1981. The Smiths planned the garden to follow the form of a cathedral: "It had a central great hall or nave, and from that – in every direction – ran hallways leading to other rooms and on to others, with niches and passageways of every description. The nave and other rooms were the grassy plots; the walls were trees, shrubs, and bamboo; the pillars were old tree trunks."[2]
