The ambulatory (Latin: ambulatorium 'walking place') is the covered passage around a cloister or the processional way around the east end of a cathedral or large church and behind the high altar.
Ritual circumambulation or parikrama around a stupa or cult image is important in Buddhism and Hinduism.
The Buddhist chaitya hall always allowed a path for this, and the Durga temple, Aihole (7th or 8th century) is a famous Hindu example.
The term is also used to describe a garden feature in the grounds of a country house.
A typical example is the one shown, which stands in the grounds of Horton Court in Gloucestershire, England.
