Right at the centre of Park Güell is the large esplanade which the original plans called the Greek Theatre and which has more recently been rechristened as Plaça de la Natura (Nature Square). Its original name was due to the fact that it was planned for staging large open-air shows that could be watched from the surrounding terraces. Although Gaudí always respected the lie of the land, this large square is artificial. Part of it is dug into the rock, while the other part is held up on top of the hypostyle room. On the stairway side it is bounded by the undulating bench covered with tile-shard mosaic planned by Josep M. Jujol, acting as a balustrade, and on the mountain side by a retaining wall finished with large capitals made to look like palm trees.
