A map of Österby manor in Uppland from 1688 by a quite good cartographer named Petter Arosander, which I had the oppurtunity to register this week. The manor itself seems to have been replaced by a more modern one in later centuries though the foundations must still remain. The location of the church ("Ålands kyrka") in the northwest corner of the map remains intact. This was founded in the 15th century. The church village represented by the lonely house (the rest of the older village is located just west of the river) close to the bridge have even older origins and the name Åland can be traced to the 13th century.
