Jēkabpils ( pronunciation ; German: Jakobstadt; Polish: Jakubów) is a city in southeastern Latvia roughly halfway between Riga and Daugavpils and spanning the Daugava River. Historic Jēkabpils lies on the left bank, in Selonia while historic Krustpils (German: Kreutzburg) lies on the right bank, in Latgale. The two cities were united during Soviet rule in 1962 under the Jēkabpils name, but retain their distinct regional character.
Jēkabpils was also formerly home to a Soviet air base.(Wikipedia)
