Side altar

The term is generally applied to altars situated in bays of the nave, transepts, etc.

[1] Side-altars may be recessed in a side-chapel, or simply built against a main aisle wall.

Before the liturgical reforms arising from the Second Vatican Council, separate Masses may be celebrated simultaneously by other priests at side-altars, even as there is an ongoing Mass at the high altar.
