The Town Hall occupies part of an old Dominican Convent built between the 16th and 17th centuries and whose Convent Church still survives. Outstanding features are the cupolas that adorn the structure of this church, and its Cloister.

An example of rationalist architecture open to the public Built by the architect and painter Erwin Broner in 1960. Cultural Interest Asset, Monument category. Donated by Gisela Broner to the Town Hall of Eivissa. Broner's work can be found in different enclaves of the city, especially in the marine neighborhoods and the port. This is his own house and is preserved just as he designed it. There are also occasional exhibitions of his artistic and architectural work, and that of other contemporary creators. Broner, of Jewish origin, was a student of Le Corbusier and played a leading role in the development of rationalist architecture on the island, along with other creators such as Josep Lluís Sert and Germán Rodríguez Arias. He got to know Ibiza in the 1930s, during his exile from Hitler's Germany. After several visits, in 1959 he settled permanently.

The old town walls, begun in the 16th century as a defence against attacks by the alliance of French and Turks, took forty years to build. They enclose an important historical legacy, declared by UNESCO a World heritage Site. The main entrance gateway is the Portal de Ses Taules.
