Church of St. Nicholas Sevastopol

Located on the Black Sea and dedicated to the patron saint of sailors, this pyramid-shaped church was built in 1857-70 as part of the Imperial Russian military cemetery by Alexey Andreyevich Avdeyev after he revised original plans by architect Andrei Ivanovich Stackenschneider.

The exterior of the church is decorated with Salviati mosaics of figures and ornaments.

Between 1887 and 1893, over 600 square meters of original paintings on the interior were replaced by mosaics by Salviati. Half of the mosaics were damaged during shelling in June 1942, but they have since been restored.

Church of the Intercession of Our Lady of Oreanda

Built in 1885 after plans by Alexey Andreyevich Avdeyev, this Georgian-Byzantine church was at one time attended by Anton Chekov.

The original Salviati mosaics were commissioned by H.I.H. The Grand Duke Constantin Romanov and covered 4,000 square feet. They were based on cartoons by Prof. Wassilieff, but unfortunately many of them - including an image of the Protection of the Virgin and nine icons - have not survived.

A very unique mosaic depiction of a teenage Christ can still be found in the dome, surrounded by eight angels, eight Apostles and four Evangelists.
