| This mosque in Córdoba, Spain, was begun in ad 786, while the city was the capital of Moorish Spain. Although the mosque became a Christian cathedral after the Roman Catholics of Spain captured Córdoba in 1236, the building retains its Islamic heritage. The mosque features columns that support horseshoe-shaped arches decorated with stripes of alternating colors. Layered in two tiers, these distinctly Moorish arches convey a light and airy feeling to the interior of the building. |
