Enfilade (architecture)

Plan of a building with three separate enfilades (marked red). Note alignment of doors between rooms to create a vista.

In architecture, an enfilade is a series of rooms formally aligned with each other. This was a common feature in grand European architecture from the Baroque period onward, although there are earlier examples, such as the Vatican stanze. The doors entering each room are aligned with the doors of the connecting rooms along a single axis, providing a vista through successive rooms. The enfilade may be used as a processional route and is a common arrangement in museums and art galleries, as it facilitates the movement of large numbers of people through a building.
