Church of St. Nicholas, Tbilisi, Orthodox church at Narikala Fortress, Tbilisi, Georgia

The Church of St. Nicholas stands on the old foundations inside Narikala Fortress, rebuilt in 1996 by architect Tariel Kiparoidze. The new structure is a slightly elongated rectangle in plan, built of Georgian brick and cut stone, its exterior faced with light-coloured carved stone and ornamented. The interior is fully painted with frescoes.

A church dedicated to St. Nicholas stood in Narikala Fortress by the 12th century and was mentioned by Prince Vakhushti in 1730. After Georgia's annexation by Russia, General Yermolov turned it into a gunpowder store in 1818; a powerful explosion in 1827 destroyed it almost to the foundations. The present church, built from 1996 on those foundations, was consecrated in 1997 by Patriarch Ilia II.

The church is dedicated to St. Nicholas, and the rebuilt interior is fully painted with frescoes. In October 2017 Mamia Alasania, a senior Georgian officer killed in Abkhazia in September 1993, was buried with military honours in the churchyard after his body was found in Abkhazia and brought to Tbilisi.

The easiest way to reach the church is by cable car from Rike Park up to Narikala Fortress, which saves you from climbing a steep hill. The ride also gives you views of the city as you make your way up.

The 1966 excavations revealed that the medieval church was a "cross-inscribed" type, with a dome resting on the altar's shoulders and two round pillars; traces of plaster and painting survived on a single brick column, and the stonework bore marks of intense fire and explosion. The 1996 rebuilding incorporated the surviving 13th-century fragments into the new walls.
