 Another common feature of Gothic cathedrals in France was a labyrinth or maze on the floor of the nave near the choir, which symbolised the difficult and often complicated journey of a Christian life before attaining paradise.Most labyrinths were removed by the 18th century, but a few, like the one at Amiens Cathedral, have been reconstructed, and the labyrinth at Chartres Cathedral still exists essentially in its original form.Although Christianity played a dominant role in the Gothic sacred architecture, Jewish communities were present in many European cities during the Middle Ages and they also built their houses of prayer in the Gothic style.
