The Guinigi Tower (1390) in Lucca is 44m tall with 7 holm oak trees growing from a roof garden at the summit. The trees have been there since the tower was built — the Guinigi family planted them as a symbol of rebirth and renewal. The effect from below: a medieval brick tower with a small forest sprouting from the top, silhouetted against the Tuscan sky. The effect from above (230 steps): a panorama of Lucca's rooftops, the complete circuit of Renaissance walls, the Apuan Alps in the distance, and the strange sensation of standing among oak trees at 44m altitude inside a medieval city.
The climb: 230 steps, spiral staircase, narrow (single file in places). The roof: A small garden — the 7 oaks provide shade, benches allow you to sit. The view: 360° — Piazza dell'Anfiteatro (the oval piazza built on a Roman amphitheatre), the Duomo, the Torre delle Ore (clock tower), and the complete ring of walls (4.2km, tree-lined, walkable/cyclable). Best at sunset: golden light on terracotta roofs, the Alps turning pink.
