In 1866, a commission led by Albert Lindhagen produced a city plan for the ridges ("malmarna") designed to offer citizens light, fresh air and access to Swedish nature by mean of parks and plantations. To this goal, he proposed a system of esplanades culminating in Sveavägen, a 2 km long and 70 m wide boulevard inspired by Champs Elysées. 1877–80 new city plans were finally passed for central Stockholm, which made the city well-prepared for the major expansion that followed. During the 1880s more than 2.000 buildings were added on the ridges and the population grew from 168.000 to 245.000. At the end of the century, less than 40 per cent of the residents were born in Stockholm.
