 In the late 1960s, Dimitrios Oreopoulos, a Greek-born doctor at the hospital, arranged to have seeds from the Tree of Hippocrates in Kos planted on the hospital grounds to commemorate the proposed expansion of the hospital.One of the trees created from the seeds, in the grounds of Erskine House, became too large to transplant to the tower building and was left in place.The tree, which remains surrounded by modern developments and is described as "an oasis of calm and a symbol of hope for patients, staff and students", was named Northern Ireland's Tree of the Year for 2017 in a public vote.
