Lucca’s wall circuit grew over several centuries. The ring that still shapes the city took form as a Renaissance defence, built for an age of artillery and now carried around the historic centre as a public park. Twelve earth-filled curtains link the city’s bastions along a circuit of about 4.2 kilometres. Inside the circuit, the Piazza dell’Anfiteatro offers another view of how Lucca’s earlier layers remain part of the living city.
The defensive fabric is not uniform. Compacted earth faced with sloping brick forms the Renaissance works, while a long northern stretch reuses medieval limestone masonry. Remains of semicircular towers from that earlier wall can still be seen.
Trees first appeared in 1546, mostly white poplars, before the walls became a formal promenade. Elisa Baciocchi’s 1807 decree allowed evening walks on one section between Porta San Pietro and Porta San Donato. The definitive nineteenth-century promenade arrangement came under Maria Luisa di Borbone, with Lorenzo Nottolini’s central carriage way and two side paths for pedestrians. Plane trees are among the species on the walls today, alongside other kinds of trees.
Today the wall-top avenues and bastion gardens make a raised public landscape around the city. Follow a short section for glimpses of roofs, churches and gardens, or complete the 4.2-kilometre circuit on foot or by bicycle. A relaxed walk takes about an hour before pauses; the changing views into Lucca and out toward the surrounding landscape are a reason to allow longer.
