Akhty Fortress, Military fortress in Akhty, Dagestan, Russia.

Akhty Fortress is a pentagonal Russian fortification with bastions at its corners, built in 1839 in the village of Akhty on the right bank of the Akhtychay near its mouth, where two rivers flank the site. It comprised defensive walls, soldiers' barracks, an Orthodox church and a powder magazine; a ditch with stone walls 4.57 m high and 1.06 m thick once surrounded it.

The fortress was built in 1839 by Russian military forces during the expansion of imperial control over Dagestan's mountain regions. It served as part of a broader strategy to secure the empire's southern frontier.

The fortress shows how local building craftsmanship and Russian military design came together in this structure. You can see how builders used local materials while combining techniques from both traditions.

The fortress is officially closed to visitors, but no control is enforced, so entry is in practice possible for anyone. There is no maintenance, many structures are in disrepair and cows graze on the grounds. It stands on the right bank of the Akhtychay near its mouth, enclosed by two rivers on two sides.

The fortress was built in just forty days in 1839, after General Yevgeny Golovin's Samur campaign subdued the free societies of the Samur valley. It then became the residence of the head of the Samur district. In 1848 Shamil's troops besieged it from 14 to 22 August and blew up the powder magazine, but General Argutinsky's measures saved the garrison.
