Oktyabrsky Island

The island, covering about 10 square kilometres (3.9 sq mi), is immediately east (upriver) of the city's historic centre.

In the 2010s the island was extensively redeveloped around the Kaliningrad Stadium, constructed for the 2018 FIFA World Cup held in Russia.

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.

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.

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.
