The Parterre is the formal garden directly alongside the Royal Palace, a structured arrangement of geometric beds, clipped hedges, fountains, and sculpture in the French style that was fashionable in Bourbon Spain. It was redesigned in the early 18th century and has retained its formal character since.
The garden's central axis runs from the palace facade to the riverbank, creating a vista that frames both the building and the Tagus beyond. Walking through it in the morning before the crowds arrive is a particular pleasure. The fountain of Hercules and Antaeus is the centrepiece, and the pruned hedgerows create satisfying geometric patterns when seen from the palace upper floors.
