Verchojansk in Yakutiya (in the north east of Russia) is the coldest place on earth. There is a weather station on Antarctica (Vostok, owned by the Russians) that once measured –89.2° C, but Verchojansk actually is a real town. It was founded as a fort in 1638 and the main activities are tin and gold mining.
Some data:
- On February 7 in 1892 the lowest temperature ever outside Antarctica was measured, -69.8° C (about -90° F).
- The so-called January isotherm is at -50° C.
- The largest variations in temperature on the earth over the year are measured in Verchojansk; between –70° and +37° C.

info from my own memory, and for a few exact temperatures.
