The Neuer Pregel, the northern branch of the river, separated Lomse from Kneiphof to the west, Altstadt to the northwest, and Löbenicht to the north.
Kneiphof feared that Altstadt's control of Lomse would lead to a trade war; in 1434 Grand Master Paul von Rusdorf negotiated a compromise in which only sties and barns would be built at a prescribed distance from the river.
[1] By the Rathäusliche Reglement of 13 June 1724, King Frederick William I of Prussia merged Altstadt and Lomse into the united city of Königsberg.
[4] Burghers from insular Kneiphof began to settle in Lomse after the completion of the Honigbrücke (Honey Bridge) connected the two islands in 1542.
King Frederick II financed a mulberry plantation (Plantage) in Lomse in 1742, but the plants froze during the harsh winter of 1771.
