Nikolsky Garden, Garden near St. Nicholas Naval Cathedral, Saint Petersburg, Russia.

Nikolsky Garden is a green space beside the St. Nicholas Naval Cathedral with walkways and seating areas for strolling. The grounds feature several monuments and memorial sites dedicated to sailors and naval history.

The garden dates to the 18th century, laid out between the Kryukov Canal, the Griboyedov Canal, Rimsky-Korsakov Avenue and Nikolsky Lane. The St. Nicholas Naval Cathedral was built in its centre in 1753–1762, giving the garden its name, and the four-tier bell tower with a spire rose on the Kryukov Canal in 1755–1758. In 1873 a square funded by merchant O. Tupikov was laid out on the empty square to the north and, at the emperor's wish, merged with the church garden; the layout was reworked in 1874–1875.

The garden takes its name from the St. Nicholas Naval Cathedral, built at its centre between 1753 and 1762. A city legend tells that merchant O. Tupikov offered to lay out the square at his own expense in exchange for its paving stones, on condition he also build a fence. The clergy opposed Emperor's wish to merge the church garden with the public square, but had to yield.

The garden is a rectangular 0.725-hectare plot bounded by the Kryukov Canal embankment, the Griboyedov Canal embankment, Rimsky-Korsakov Avenue and Nikolsky Lane, on Nikolskaya Square. Enter from any of these sides; the four-tier bell tower with its spire stands on the Kryukov Canal side. The layout is landscape-regular, so paths cross the grounds between the cathedral and the monuments.

The granite obelisk behind the cathedral fence, unveiled in 1908, honours the crew of the battleship Alexander III, lost at the Battle of Tsushima. Architect Yakov Filatey built it to a sketch by naval officer Prince Nikolai Putyatin; its appearance changed during the 1973 restoration.
