Mudéjar art, or Mudéjar style, was a type of ornamentation and decoration used in the Iberian Christian kingdoms, primarily between the 13th and 16th centuries. It was applied to Romanesque, Gothic and Renaissance architectural styles as constructive, ornamental and decorative motifs derived from those that had been brought to or developed in Al-Andalus. These motifs and techniques were also present in the art and crafts, especially Hispano-Moresque lustreware that was once widely exported across Europe from southern and eastern Spain at the time.

Muqarnas, also known in Iberian architecture as Mocárabe, is a form of three-dimensional decoration in Islamic architecture in which rows or tiers of niche-like elements are projected over others below. It is an archetypal form of Islamic architecture, integral to the vernacular of Islamic buildings, and typically featured in domes and vaults, as well as iwans, entrance portals, or other niches. It is sometimes referred to as "honeycomb vaulting" or "stalactite vaulting".
