St. Catherine's Armenian Church (Armyanskaya tserkov). In 1770 Empress Catherine II gave her permission for this church to be built on
land previously owned by herself. The architect was M. Velton who also designed the building at number 42. The church was closed in 1930 and
used as a workshop and warehouse for many years. In a very dilapidated condition it was returned to the Armenian parish in 1990, since when it has been lovingly restored.
