In architecture, an alcove is a small recessed section of a room or an arched opening (as in a wall). [1] The section is partially enclosed by such vertical elements as walls, pillars and balustrades. [2]
The word alcove originates from Arabic القبة ( [ʔalqubːa] ⓘ ), al- 'the' and qubbah 'vault' (through the Spanish alcoba).[ citation needed ]
