Built on the site of a mosque in the early twentieth century, the Russian Church is a stunning golden-domed building with an emerald spire and an exuberant mosaic-tiled exterior, which conceals a dark, candle-scented interior. The nearby Aleksandar Nevski Cathedral is one of the finest pieces of architecture in the Balkans. Financed by public subscription and built between 1882 and 1924 to honour the 200,000 Russian casualties of the 1877–78 War of Liberation, it’s a magnificent structure, bulging with domes and semi-domes and glittering with gold leaf. Within the gloomy interior, a beardless Christ sits enthroned above the altar, and numerous scenes from his life, painted in a humanistic style, adorn the walls. The crypt, entered from outside, contains a superb collection of icons from all over the country.
