Principe Real Garden

This guide to Príncipe Real Garden in Lisbon starts with the metal frame wrapped around the giant tree at its center — not there to prop the tree up, but to hold it in. It traces the story of the Mexican cypress Lisbon calls the Cedar of Buçaco, planted here in the 1860s from a lineage the Barefoot Carmelite friars first carried from Central America to Portugal in 1644, and the farmers' market and poetry festival that still gather beneath its twenty-metre canopy. Listen for the faint citrus scent from its leaves as you stand under the branches.
