Paraskeva Pyatnitsa Chapel, Orthodox chapel on Karaulnaya Hill, Krasnoyarsk, Russia

Paraskeva Pyatnitsa Chapel is an octagonal brick chapel on Karaulnaya Hill, plastered and painted a single tone, rising about 22 m to the cross. Pilasters mark the eight corners, kokoshnik arches sit above each face, and a faceted green tent roof with dormer windows ends in a small gilded onion dome and Orthodox cross. Each wall face is 2.4 m wide and 7 m high.

The chapel was built between 1852 and 1855 by architects Yakov Alfeev and Yakov Nabalov. It replaced an earlier wooden structure that was funded by merchant Novikov in 1805.

The chapel takes its name from Paraskeva Pyatnitsa, a saint whom Orthodox tradition links with Friday, the day of her commemoration. It stands on Karaulnaya Hill, called Kum-Tegai in Turkic, where a pagan shrine of the Kachin Tatars preceded the Cossack watchtower. Newlyweds still come here to declare their love, and the site draws pilgrims from the city and beyond.

The chapel stands on the summit of Karaulnaya Hill, reached by a staircase rebuilt in 2012 that leads up past the cannon on the hill. The paved area around the building serves as a viewing point over the central part of Krasnoyarsk. The interior is small and connects to the tented upper section by a hatch.

The chapel appears on the reverse side of the Russian 10-ruble banknote, making it a nationally recognized architectural monument. This feature makes it a familiar symbol for people across Russia.
