In the center of Moscow, in Zamoskvorechye, there is a church dedicated to the Holy Martyr Clement. From his biography, it is known that Clement lived in the 1st century. At the age of 24, he met the Apostle Peter and became one of his disciples, and then his successor – the saint ordained him as the Bishop of Rome. Pope Clement converted many people to his faith, and eventually, Emperor Trajan ordered him to be sent to hard labor in the quarries near Chersonesus. Despite the hardships, Clement continued to preach: the number of his followers grew rapidly. In 101, he was drowned, tied to an anchor, but the waters of the Black Sea receded every year on the day of Clement’s death, revealing the entrance to the cave where his remains were kept. In the 9th century, Saints Cyril and Methodius found the relics of the holy martyr: parts of them were transferred to Rome and Kiev. The relics of Saint Clement are considered one of the first Christian holy treasures in Russia. Saint Clement is venerated by both Catholics and Orthodox Christians and is considered the first heavenly patron of the Russian land. In Inkerman, there is a cave monastery named after him. In the St. Clement's Church in Zamoskvorechye, a particle of his relics is kept.
