Formentera.

The hundred square kilometres which form the surface of Formentera are mostly fiat and stony, as can be observed from the La Mola promontory from which practically the whole of the island is visible.
The predominant element on the island is the "dry stone" wall, built from stones removed from cultivated land, which separates properties and protects areas of cultivation, forming a rectilinear network which, seen from the plain, has th appearance of a labyrinth. Architecture on Formentera is generally more humble than that of Ibiza.
The churches are composed of a single rectangular nave with doors at the front and few additions. The church of El Pilar, whitewasched on the outside, is the one which most resembles rural churches on Ibiza. The church of San Francisco stilll preserves its original appearance and its sober image is witness to its defensive purposes which, complemented by the watchtowers, allowed the permanent settlement of the town.
Old rural houses on Formentera are of the same type as their Ibiza counterparts, though they are less varied and picturesque since they are situated on level ground. This was the predominant type on formentera until the middle of last century.
The type which predominates today has a rectangular ground plan with a gable roof, similar to the most elementary Catalan "masia" (farmhouse). The porch added to the main façade is the element which differentiates these houses.
The proximity between the two islands makes the previous comments on twentieth-century architecture on Ibiza applicablre to Formentera also.
