The Hospital for the Poor of Jesus Christ of the Town of Llançà was founded in the 17th century. The first references we have of this institution dates back to 1616. This hospital for the poor, as it is known in the Latin records -Hospitalis Pauperum- had had several functions: attend the needs of the poor sick people of the town, the people who lived alone or in financial need and there found a refuge to heal or to die with more dignity. This institution was subsisted by profits obtained from the benefits of the citizen taxes and donations. The maintenance of the building was the responsibility of the Municipal Council first and then of the Town Hall.

The last documented references are from the year 1925, when the building was already in a ruinous state. The old hospital building was demolished in the seventies of the 20th century, and the Telefónica headquarters was built on its site.
