Kaliningrad 

A piece of land completely separated from the rest of Russia.
Prior to Russia owning it It was formerly owned by Germany until its surrender in WW2.
Kaliningrad is modern day Prussia and although Prussia was german Kaliningrad’s demographics is now mostly russian so the likelyhood of Kaliningrad joining germany or being independent from Russia is unlikely especially with Vladimir Putin currently in power.

The glory days Prussia is gone and all we have left is Kaliningrad.

Kaliningrad 

a sketchy naval city disconnected from the rest of Russia. Formerly Konigsburg, Prussia, it became a shithole during the Soviet times and is home to the ugliest building in Europe (the House of the Soviets)

It's that random piece of Russia between Poland and Lithuania

Don't go to Kaliningrad, it's ugly as fuck.
