Kazanskaya Chapel in Yaroslavl, Orthodox memorial chapel on the Kotorosl embankment in Yaroslavl, Russia

The Kazanskaya Chapel is a memorial chapel on the Kotorosl River embankment in central Yaroslavl, facing the Holy Gates of the Spaso-Preobrazhensky Monastery. Its upper part is an octagon on four arches with perspective portals, topped by a tent roof and a gilded onion dome on a narrow drum. Diagonal buttresses give the structure the look of an obelisk. Inside, a small bell hangs beneath the octagon, and a stained-glass screen with a full-length Christ stands in the eastern arch.

The chapel commemorates the Second People's Militia, formed in Nizhny Novgorod in 1612 to free Moscow. It moved up the Volga and halted in Yaroslavl for four months, its headquarters in the Spaso-Preobrazhensky Monastery, while the city served as the state's capital. On 27 July 1612 the militia left the monastery walls for Moscow. The chapel, designed by architect G. L. Dainov, was consecrated in August 1997 for the 385th anniversary of that departure.

The chapel is a memorial to the 1612 militia, with the inscription on the base plate reading "To the People's Militia of 1612 from grateful descendants". Relief icons on the octagon's faces show the Kazan Icon to the west, St George to the north, Archangel Michael to the south and the Image of Christ Not Made by Hand to the east. The Kazan Mother of God is venerated as patroness of the Russian army and of Yaroslavl.

The chapel stands on the Kotorosl embankment directly in front of the Holy Gates of the Spaso-Preobrazhensky Monastery, a short walk from the monastery's main entrance. It is a small open memorial structure rather than a parish church, so visits are brief and fit easily into a walk along the river.

The chapel appears on Russia's 1000-ruble banknote, which shows Yaroslavl's embankment with the chapel in the foreground. Its silhouette, an octagon on four arches with diagonal buttresses, is often compared to a rocket. Inside hangs a small bell above a plaque reading "To the People's Militia of 1612 from grateful descendants".
