The history of a Trinity Cathedral began on July 12, 1733
when large field tent was erected here for the soldiers and
officers of the Ismailovsky Regiment of the Russian army. First
permanent wooden church was constructed here in 1754- 56. Flood
of 1824 damaged it beyond repair and a new Russian Emperor
Nicholas I ordered the construction of a new Trinity Izmailovsky
Cathedral between 1828 and 1835.
