English: Plan of Elburg in The Netherlands, "drawn by Wim Boerefijn," based on the cadastral plan of 1830. Elburg was founded in 1392 by Arent toe Boecop, steward of the duke of Gelre. Arent seems——to have acted as a private entrepreneur. He had bought a piece of land next——to the existing town. And he obtained permission from his lord to extend and rebuild the town, and to resettle the population of the surrounding area, selling the house lots to the settlers. The highly symmetrical layout is based on a canalised river flowing in a northeast-southwest direction and an intersecting street running in a northwest-southeast direction. The symmetry is disturbed, however, by the church in the eastern corner and by the pre-existing street (the only curved one in the whole town) on the northwest side. The corner bastions and the wide outer ditch were added in the late 16th century.
