The Fernleaf Beech of Palazzo Doria-Tursi
Fern-leaved Beech (Fagus sylvatica f. asplenifolia). roughly 100-180 years (girth-based estimate, no dated source). Free. Stands in the courtyard of Palazzo Doria-Tursi, a Rolli palace (UNESCO) that now houses Genoa's city hall and the Strada Nuova Museums; the main courtyard and staircase are generally open to the public without a ticket during opening hours, per general sourcing on the palace. Not personally confirmed the tree itself is unobstructed from the courtyard this pass.

The Poet's Holm Oak of Montesignano
Holm Oak (Quercus ilex). roughly 150-300 years (girth-based estimate, no dated source). Not confirmed this pass. Via Mogadiscio is a residential street in the Montesignano district; independent geocoding places it at roughly the same coordinates as the register (44.4389, 8.9665), and the Liguria regional listing ties the tree to the church of San Michele Arcangelo rather than a private garden, which is a good sign, but I did not find a source stating the tree stands on public ground or is visible from the street. A local civic-tech initiative is literally named 'Il Leccio di via Mogadiscio' after it (Genova Digitale ran information sessions there), which suggests it functions as a known local landmark rather than a hidden private specimen, but that is not the same as confirmed public access.

The Holm Oak of San Pantaleo
Holm Oak (Quercus ilex). roughly 200-350 years (girth-based estimate, no dated source). Not established this pass. No second source found describing what stands at this address or whether the tree is visible/accessible from the street.

The Great Camphor Tree of Via Romolo Gessi
Nepal Camphor Tree (Cinnamomum glanduliferum). roughly 150-250 years (girth-based estimate, no dated source). Not established this pass.
