The Kazan Cathedral in Feodosia is an outstanding example of architecture and religious life in the city. Founded in the early 20th century, it remains a popular place for baptisms and weddings. The history of its creation deserves special attention. The temple was built in honor of the miraculous salvation of Emperor Alexander III's family after the crash of the royal train on October 17, 1888. Funds for the construction were raised worldwide, and the land was provided by local residents who owned plots near the estate of Count Nikolai Fedorovich Heyden. The count transferred his property to the Toplovsky Monastery.

The fundraising and preparation for construction took many years, and the actual work only began in 1907. It was decided to build the new temple on the site of the wooden church of the Toplovskaya Monastery, and by 1911, the construction was completed. The project was developed by architect Keil, who created the temple in the Russian-Byzantine style. The consecration took place solemnly, with the participation of Bishop Theophan of Taurida and Simferopol, who left Russia nine years later during the Russian exodus. After the arrival of Soviet power, the temple was desecrated and closed until 1943, when it was reopened by the German authorities. During this time, the cathedral was actively visited by Orthodox Romanians who were in Crimea. Later, the cathedral was restored, and today its foundation is reinforced, ensuring its preservation.
