Map from 1896
Map of Sundby village centre 1896. The names are common Danish street names like Østergade, Danmarksgade, etc. However when Sundby joined Copenhagen in 1902, names were changed to avoid confusion. Names of european countries, towns and regions we used at new street names.
Take the passage to the left of the old school, towards Valdemarsgade. Soon you wil get to "Rolighed".
At Rolighed, look at the ornaments, and enter the year the house was built.
