1789
The king commissions Cayetano Soler to carry out the Plan of Reforms, which included the construction of new public buildings, industries and educational centres. A ramp is begun to make the climb up to EI Portal de las Tablas easier. Water is brought to a public fountain from San Rafael. Plans are drawn up for new towns in all the parishes; the construction of Santa Eulália del Rio is begun with the first public fountain and the planting of the poplar grove. A hundred boundary stones are put into position to mark the limits of the "quartons". At the same time Cayetano Soler establishes the Nou Sistema (New System), which implied a political and economic transformation, The suburb of La Marina grows considerably during this century. A low wall, called L'Estacada. is built (closing La Marina from the San Juan bastion to the beach, and with a gate opening into Calle de la Cruz), and measures are taken to limit its growth, for defense reasons. Maritime traffic and privateering increases and, at the end of the century, Ibiza and Formentera become the province of Ibiza. A Royal Command establishes the foundation of a town in each of the recently created parishes. Cayetano Soler demarcates 18 towns. The attempts to group the rural population around churches and town halls fails due to the country people's independent character.
