The buildings, which were built outside the walls of Ibiza Town in earlier times, can be divided into three groups: white, cubic farmhouses, stone towers on the coast and inland as well as churches, which also function as a fortress. Furthermore, windmills were a formative phenomenon.
The traditional farmhouses in Ibiza are spread across the country. The classic farmhouse consists of cubic elements that are plastered in bright white. They have a flat roof, which is sometimes used as a terrace. As a rule, the windows are small and small in number. Sometimes the windows weren't glazed.
The house consisted of a main cube, which is supplemented by several secondary cubes depending on the state of the finca. So the size of the house could be adapted to the family situation.
This architecture of the fincas inspired and influenced the architects of the Bauhaus period such as Walter Gropius or Le Corbusier.
The more recently built houses in the country are more or less based on the traditional shapes and colors, whereby the proportion of windows increases.

Formative are the stone towers, which can be found in exposed places along the coast, but also inland. They served the security of the population in the event of pirate attacks and were used to monitor approaching ships. When enemy ships were sighted, signals could be passed from tower to tower in order to be able to quickly warn the entire island population.

Fortified churches
The fortified churches are another architectural feature of the island. Churches often served not only as places of worship, but also as useful fortresses. In the event of pirate attacks, the population retreated to the fortified churches and effectively defended themselves from there.
Some of these churches even had impressive cannons, some of which were positioned on the roof.

In the past, windmills were of great importance and can still only be seen in fewer places. Sometimes they are quite simple. However, the Sant Antoni windmill is impressive in terms of size and design.
