In addition, Danish merchants who settled in Iceland, after the ban was lifted in 1770, often ran large households characterised by a mixture of Danish and Icelandic customs. Reykjavík, which developed as village by the end of the 18th century, began to grow and became a center of a melting pot of Icelandic and Danish culinary traditions. Fishing villages formed in the 19th century, many located by the trading harbours, which previously had featured little more than a natural harbour and a locked warehouse nearby. The Danish influence was most pronounced in pastry-making, as there were few native traditions in this craft. Ethnic Danish bakers began to operate around the start of the 20th century in both Reykjavík and Akureyri. Some Danish pastry-making traditions have survived longer in Iceland than in Denmark.
