The Orange Courtyard of the Mezquita

Ninety-eight bitter orange trees stand here in rows that line up with the columns of the prayer hall next door, so the courtyard reads as the building continuing outdoors into the light. It may be the oldest surviving garden in Europe: the enclosure goes back to the mosque founded in 784, orange trees are recorded in it from at least 1512, and the shallow channels that link the tree pits still carry the water that feeds them. In 2001 workers found a tenth-century cistern twelve metres beneath the paving, built to hold twelve hundred cubic metres so that washing and irrigation would never stop. Be honest about the trees themselves: they are ordinary Seville oranges, replaced one by one as they fail, so the grid is old and the individuals are not. What is worth timing a trip for is the last days of March, when the whole courtyard flowers at once and the scent of azahar carries out into the surrounding streets. Since 2026 the chapter has turned the bitter harvest, previously thrown away, into vinegar.
