The Laberint d'Horta is a cypress maze in the hills above Barcelona. About seven hundred and fifty metres of hedge are still cut to the plan they were given at the end of the eighteenth century, with a statue of Eros standing where the paths finally resolve. Around it climbs a garden of stone terraces, ponds, channelled water and statues from Greek myth, laid out from 1791 by a marquis with a serious interest in mathematics and an Italian architect he brought in.
Everything down here is geometry. Above the maze the ground climbs through a later, looser romantic garden of ponds, a false ruin and a cascade, and the temperature drops as you go up under the trees. The Desvalls family kept the place private and sold it to the city in 1967; it opened to the public in 1971. The rules that came with it are still strict: no dogs, no bicycles, no ball games, no picnics, and a limit on how many people are let in at once, because the hedges are the exhibit.
