The Vladimir Cathedral in Chersonesus.
The Saint Vladimir Cathedral is a Neo-Byzantine Russian Orthodox cathedral on the site of Chersonesos Taurica. It commemorates the presumed place of St. Vladimir's baptism.
The author of the project of St. Vladimir Cathedral in Chersonese was academician David Grimm. According to his plan, the Cathedral had to be built in Byzantine style. The construction took 15 years and was finished in 1874-1876.
During World War II the cathedral was destroyed. The work on its restoration began in the late 1990s, even though it was made more active only in 2000. - in: wikipedia
