In the thirteenth century, the old Barcino experienced a transformation that was caused by necessity. The city grew, the walls became small and new ones were built. New neighborhoods and new jobs appeared. Those who worked in the same kind of job were settled all in one place. In the Sombrerers (milliners) street were settled the guild of milliners, manufacturers of hats and caps made of wool, silk, yarn or thread. They worked with needle and this gave the original name of needle milliners. It was considered one of the seven silk arts.
