Assumption Cathedral is one of Astana's most visible Orthodox landmarks, a broad, pale church crowned with gold domes on the older right bank of the city. Inside, the iconostasis, painted surfaces, and candlelit devotional atmosphere contrast sharply with the futuristic monuments across the river.
The cathedral is active, so visit respectfully and avoid treating services as a show. It is worth pairing with a walk through the right bank neighbourhoods, where Astana feels less like a planned capital and more like a lived-in northern city.
