The building which nowadays is as one of the protagonists of Palma?s maritime façade was originally the headquarters of the School of Merchants.
Guillem Sagrera, Majorcan well-known sculptor in the XV century, was entrusted to erect an adequate place for the merchant?s tasks and necessities. Therefore, during Martí l'Humà?s rule the works at La Lonja were commenced.
The result was a simple building, of a balanced composition, showing the island?s Gothic style. Rectangular shaped, it is divided into twelve sections, separated by six fluted columns which open up into ribs of a groined vault.
