Ignatovo Sphere, hollow man-made sphere north of Dubna, Russia
Ignatovo Sphere is a destroyed spherical structure in Russia that once served as a radar dome. The abandoned concrete construction stands today as a ruin in the landscape, showing traces of its original technical purpose.
The dome was built during the Soviet era as part of the radar system developed for airspace monitoring. It was later abandoned and fell into the deteriorated state visible today.
The site is located away from urban centers and can be reached by local transport. Visitors should pay attention to safety when exploring the ruins and wear sturdy footwear.
The perfectly round shape of the dome appears surreal among the ruins and gives the place an unexpected geometric quality. Despite deterioration, this sphere remains an intriguing example of Soviet engineering left to nature.
