Historically, the outpost is described as part of the Kolyvano-Kuznetsk defensive line, the chain of forts that protected the silver-mining region of the Altai in the 18th century. Its construction is dated to 1765-1770 and its purpose was to guard the silver-smelting mines and the Empire’s southern frontier. It had a four-sided earthen redoubt from which only the ditch survived, in the valley of the Bolshoy Tigirek river near several caves.

The site’s current state is unclear. A Russian news report on an expedition to the reserve says the group visited the place where the Tigirek fortress used to stand, which suggests little or nothing of the structure remains above ground. The sources also disagree on its shape: one calls it a four-sided redoubt, another a star fort, but the available satellite imagery should settle that.

One of the most iconic locations of the 1956 revolution in Hungary, Széna tér (Hay(-market) Square) is closely tied to Budapest’s 20th‑century urban growth, evolving from a peripheral market area into a busy transport hub by the mid‑1900s. Its strategic position near the Várhegy (Castle Hill) and major roads made it a natural gathering point during periods of political upheaval.

In 1956, Széna tér became the main resistance center in Buda. A group of mostly young workers and apprentices occupied buildings around an active metro construction site and built barricades from railway wagons. Under the leadership of János Szabó, they controlled the area, stopped vehicles for inspection, and engaged in several armed clashes with state security forces. Although smaller than the famous Corvin Passage group, the Széna tér fighters held a key strategic position and negotiated temporary ceasefires with nearby army units.

The decisive fighting occurred on November 4, when Soviet armored units launched a full assault. The defenders, lacking heavy weapons, were overwhelmed after intense machine‑gun and artillery fire. Many fled, others were captured, and the resistance collapsed. In the reprisals that followed, fourteen members were executed and many more imprisoned. Széna tér’s role became one of the defining stories of the revolution’s Buda front, symbolizing determined but ultimately doomed civilian resistance.

This is the pole of cold monument in Verkhoyansk, Sakha Republic, Russia erected in 1988. On January 15, 1885, S. F. Kovalik recorded a temperature of −67.8 °C here.

Opponents of Verkhoyansk dispute this argument on the grounds that temperature measurements had not yet been taken in Oymyakon at the time. This objection was refuted by the repeated recording of the same temperature in February 1933. At the same time, the temperature in Oymyakon was “only” -67.7°C.

Interestingly Verkhoyansk holds both the record for the highest temperature ever recorded north of the Arctic Circle, with 38.0 °C (100.4 °F), and the record for the lowest temperature ever recorded in Asia, −67.8 °C (−90.0 °F), the largest ever temperature range recorded. The cold record is shared with Oymyakon.

It is the coldest inhabited place north of the Equator but the absolute cold record was measured at an uninhabited automatic meteorological base in Greenland.
