What is "aklansk"

Aklanski Ostrog (Russian : Акланский острог) or Penzjinskoje zimovje (Пенжинское зимовье; "wintering place Penzjina") was a fortified city in Russia between 1679 and 1804 on the river Oklan (then Chajachla or Aklan), into which the Penzjina flows. The city, established by Vladimir Atlasov as a stronghold for the Korjaken forcing jasak to pay, was not much more than a fortified place, having the status of oejezdstad. The place was also hated by the Korjaken (the place burned down several times) and the Joekagieren (which besieged the place once). The nearest place was the Ostrog Anadyrsk, on the middle reaches of the Anadyr.

Around 1680 there was a log cabin with two shelters, one for the Cossacks and Korjaakse prisoners, who Amanat were held to Korjaken to force the jasak to be invoked. Beside the house was a shed for the storage of sable skins.
