The project was completed in 2016. The garden was a popular destination for botanists and supplied plants to other gardens such as Kew. Hope erected a monument to Carl Linnaeus on the site in 1778. In the early 1820s under the direction of the Curator, William McNab, the garden moved west to its present location (adjacent to Inverleith Row), and the Leith Walk site was built over between Hopetoun Crescent and Haddington Place.
