The presence of trees inside medieval villages or in the historic heart of medieval towns is usually marginal. These urban units inherited from the Middle Ages are characterized by narrow streets and small squares. Such particularities made it impossible to plant ornamental trees such as elms, ashes, or chestnut trees, which were therefore relegated to the outskirts of the towns. This trend was reversed in the 18th century, a time when the ancestral elm of Gorbio (1703) was planted and served for a long time as a shelter for municipal council meetings.
