The Cypress of Príncipe Real

Lisbon's first legally protected tree is not a cedar at all. Everyone calls it the cedro-do-Buçaco, but the tree presiding over Príncipe Real garden is Cupressus lusitanica, a cypress from the mountains of Mexico and Guatemala with a Portuguese name it never earned. In 1940 it became the first tree in the country classified as being of public interest, decades before Portugal had a formal national registry for such things. Its canopy, once a vast gazebo-like dome some 30 metres across, has thinned with age and storms down to about seven metres of visible height, though the trunk still measures four metres around at the base. Portuguese heritage records put it at roughly 150 years old, predating most of the surrounding 19th century garden. One international tree registry claims it instead dates to around 1740, nearly twice that age, a gap nobody has resolved. Locals shelter under its remaining canopy on Saturday organic market mornings, largely unaware they are standing under a tree whose paperwork outranks almost every building in view, and whose exact age is still an open question among the people paid to know it.
