Lomse's name was of Old Prussian origin and referred to marshland. Only the western end of the island was heavily developed, with the remainder consisting mostly of meadows. The land was granted to Altstadt in 1286 and was initially used as a lumberyard and then as a warehouse quarter. 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. By the Rathäusliche Reglement of 13 June 1724, King Frederick William I of Prussia merged Altstadt and Lomse into the unitedcity of Königsberg.
Locations
Prominent roads in northern Lomse were the western Vorderlomse and eastern Hinterlomse. The latter was also known as Seilerbahn because of the rope produced there. Lomse was connected to Altstadt and Löbenicht by the northern Holzbrücke, constructed by the burghers of Altstadt in 1404. This bridge connected with Lindenstraße, which was originally the Ochsenmarkt and then a grain market. In 1838 53 linden trees were planted there; locals called it the Lindenmarkt. Much of Königsberg's Polish population was settled along Lindenstraße and the neighboring shores of the Pregel. Approval of the southern Hohe Brücke to connect Lomse with Haberberg over the southern Alter Pregel was granted in 1377, but it was not until 1500-20 that the bridge, then known as the Newe Brücke, was actually built. Burghers from insular Kneiphof began to settle in Lomse after the completion of the Honigbrücke connected the two islands in 1542. King Frederick II financed a mulberry plantation in Lomse in 1742, but the plants froze during the harsh winter of 1771. The ProtestantKreuzkirche was built along the Plantage from 1930-33. The liberalNeue Synagoge, built along Lindenstraße from 1894-96, was burned down during the Night of Broken Glass in 1938. The Kypkeanum on Hinterlomse was a dormitory established in 1778 by the philologist Georg David Kypke for students of the University of Königsberg. To the south Lindenstraße became the Weidendamm, which was named after its decorative willow trees. Weidendamm was first developed by Altstadt during the 1455 siege of Kneiphof, part of the Thirteen Years' War, and was used as a warehouse quarter. It connected to Vorstadt by the Kaiserbrücke and to Haberberg by the Hohe Brücke. Working class Weidendamm had one of the highest birth rates in the city at the start of the 20th century. Of the Seven Bridges of Königsberg made famous by the mathematical problem solved by Leonhard Euler, three connected to Lomse. Originally all were bascule bridges.
