Oktyabrsky Island
Oktyabrsky Island – Остров Октябрьский (Russian for 'October [Revolution] Island') – is an island in the Pregolya River in Kaliningrad, capital of Kaliningrad Oblast, an exclave of Russia. The island, covering about 10 square kilometres (3.9 sq mi), is immediately east (upriver) of the city's historic centre. When Kaliningrad was the German Königsberg, the island was called Lomse from Lomse (Old Prussian for 'swamps') and largely used for grazing, except for the district of Lomse at its western end. Since the 2010s the island has been extensively redeveloped around the Kaliningrad Stadium, being constructed for the 2018 FIFA World Cup due to be held in Russia.
River channels
The German name for the Pregolya River was the Pregel. The two channels of the Pregel, flowing to the north and south of Lomse Island, were called Neuer ('new') or Samländischer ('of Sambia') and Alter ('old') or Natangischer ('of Natangia') respectively.
History
A wooden bridge from Löbenicht was built in 1404, and the island was used to store wood. In the mid-15th century, the Germans built an earthen dam and began to dig canals to drain the land, converting it from unused marshes to pastureland. Outside the developed western end of the island, building houses was prohibited as the soil was unstable. In the early 17th century, the government built a second belt of fortifications around Konigsberg, which included the Wiesen-Front trench and bastion crossing Lomse from north to south. Three bridges of the famous Seven Bridges of Königsberg mathematical problem connected to Lomse.
