Ambulacrum

Ambulacrum is an architectural word that denotes an atrium, courtyard, or parvise in front of a basilica or church that is surrounded by arcades or colonnades, or trees, and which often contains a fountain.

It also can denote a walking path that trees delineate.

In the Roman architecture, the term ambulatio or ambulacrum was used to designate walkways or corridors delineated on both sides by plants or colonnades.
