The Plane Tree


Pair of Plane Trees, Platanus orientalis (Trees no. 256 & 257) Opposite the Law Library

Of note: all plane trees (used frequently in cities) shed their bark every 2/3 years – good for getting rid of certain amounts of pollution.  The seed heads are globular in appearance.

Of interest: this pair of trees are very unusual looking because of their reaction to a infection in the main trunk during the infancy of the tree.   The nodules created during this infection continue to fall off regularly.

Medicinal Garden


Medicinal garden – outside the Science Gallery.

We will take some samples of a few of the herbs here and choose based on the resultant imagery. We would like to include a herb that incorporates the sense of smell or taste to further enhance the self guided walk.

Of note: The Science Gallery have a pamphlet pertaining to this herb garden.

Oregon Maple


The Oregon Maple, Acer macrophyllum (Tree no. 312 & 319). Location: Main square

Background: brought to Europe from America. These are some of the oldest trees in Trinity College.

Of interest – the bracing system – where the tree limbs are linked by a steel cable system, which move in unison spreading the load throughout the tree.  See image below.

Of note – the tree surgeon has only a 3o seconds time frame from drilling holes for support rods to inserting rods as tree will start to repair itself closing the hole.
