According to Landnámabók, the settlement of Iceland began in Reykjavík when Ingólfur Arnarson arrived from Norway in the year 874. For over 900 years following this, there was no urban development; the city was officially founded in 1786 as a trading town and grew steadily as it transformed into its current state as the centre of Iceland's cultural, economic, and governmental activity. It is popular with tourists and is consistently ranked as one of the cleanest, safest, and most environmentally friendly cities in the world.
