The central point of the park is the huge Plaza de la Naturaloulez, with an oval shape 86 meters long and 43 meters wide. It was built between 1907 and 1913. According to the original plan, the central square was supposed to be a Greek theater, which could be used to meet and celebrate cultural and religious events. On its outer side there is a chute, decorated with gargoyles in the shape of lion heads, in order to divert excess rainwater, as well as triglyphs with motifs of flowing water. On the outer perimeter, which serves as a balcony, there is a wavy-shaped bench 110 m long. It is covered with small pieces of ceramics and glass - the work of Josep Maria Juola. The undulation of the bench gives a sequence of concave and convex modules with a length of 1.5 m each. A large part of the bench is decorated with a ceramic decor resembling Dadaist or surrealist collages. They usually carry abstract motifs, but also some figurative elements, such as zodiac signs, stars, flowers, fish or crabs. The architect also included roses in honor of the Virgin Mary and allegorical phrases in Catalan and Latin, as well as crosses and the letter J from Jujol. Trenzada were built from household garbage: tiles, bottles and pieces of dishes. The colors of blue, green and yellow that symbolize for Gaudi Vera, Hope and Mercy prevail throughout the complex. This area is not asphalted, because the water that it collects from the sediments is collected and sent through the columns that support it to an underground reservoir with a volume of 1200 m3, in order to subsequently use it to irrigate the park. The excess water goes to the dragon sculpture, which was supposed to greet visitors to the park with a fountain. There was also an attempt by Guell to establish the sale of this water in 1913 under the brand name SARVA (Sar and Ba are two Sanskrit signs, the initials Śiva and Viṣṇu, Hindu gods, which mean everything.
