Kuznechnaya Krepost, Military fortress ruins on Kuznechnaya Hill in Bishkek, Kyrgyzstan.

Kuznechnaya Krepost is a fortress ruin built on elevated ground in Bishkek, Kyrgyzstan. The stone structures sit on a high position that overlooks the surrounding city and landscape.

The site was the citadel of Jul, a Sogdian trading town on the Silk Road that existed from the 7th century and was visited by merchants from east and west. From the 15th century Kyrgyz nomads camped in the area. In 1825 Lyashker Kushbegi, a Kokand military official, seized the valley and the Kokandis built several fortifications here, including this one.

The name "Kuznechnaya" is linked to Tatar blacksmiths who, by one account, settled in this area after the fall of the Kokand Khanate. The surrounding historical district is still popularly called Kuznechka, after the hill. A self-flowing ceramic water pipe from the site is now kept in a museum.

The site lies within Bishkek itself, in the Sverdlovsk district, not far from the centre. The remains are low earthen hillocks with fragments of wall and one tower, so the ground is uneven; wear sturdy shoes. The surrounding Kuznechka quarter is mostly single-storey houses, and the hill is best viewed on foot.

The hill is known locally as Kuznechka, a name that also covers the surrounding historic district. One explanation links it to Tatar blacksmiths who settled here after the fall of the Kokand Khanate. A gravity-fed ceramic water pipe from the site is kept in a museum.
