Monument to Peter I (Peter and Paul Fortress)

Historic Centre of Saint Petersburg and Related Groups of Monuments is the name used by UNESCO when it collectively designated the historic core of the Russian city of St. Petersburg, as well as buildings and ensembles located in the immediate vicinity as a World Heritage Site in 1991. The site was recognised for its architectural heritage, fusing Baroque, Neoclassical, and traditional Russian-Byzantine influences.

The Grand Ducal Burial Vault (Russian: Великокняжеская усыпальница) is the purpose-built mausoleum of the Grand Dukes and Duchesses of Russia in the Peter and Paul Fortress. The Neo-Baroque domed structure is frequently mistaken for a part of the Peter and Paul Cathedral due to architectural similarities. A covered passageway leads from the mausoleum to the cathedral, where the Russian emperors and empresses are buried. The building was designed by David Grimm in 1896. It was constructed in order to remove the remains of some of the non-reigning Romanovs from the cathedral, where there was scarcely any room for new burials. Antony Tomishko and Leon Benois were responsible for the actual construction work. The interior is richly decorated with marble, mosaics and ormolu. Grand Duke Alexei Alexandrovich of Russia was the first to be interred in the mausoleum in 1908. The bones of eight other royals were brought to the vault from the cathedral. The last prerevolutionary burial, that of Grand Duke Constantine Constantinovich of Russia, took place seven years later. The mausoleum was expected to hold up to sixty tombs, but by the time of the Russian Revolution there were only thirteen. The Soviets destroyed the uniform tombs with a view to converting the building into a city history museum; the tombs were later restored. Grand Duke Vladimir Kirillovich was buried in the Grand Ducal Mausoleum in 1992. The remains of his parents, Grand Duke Cyril Vladimirovich and Grand Duchess Viktoria Feodorovna, were transferred from Schloss Rosenau three years later. His wife, Grand Duchess Leonida Georgievna, was buried there in 2010.

The Peter and Paul Fortress is the original citadel of St. Petersburg, Russia, founded by Peter the Great in 1703 and built to Domenico Trezzini's designs from 1706 to 1740 as a star fortress. Between the first half of 1700s and early 1920s it served as a prison for political criminals. It has been a museum since 1924.Today it has been adapted as the central and most important part of the State Museum of Saint Petersburg History. The museum has gradually become virtually the sole owner of the fortress building, except the structure occupied by the Saint Petersburg Mint (Monetniy Dvor).

The Peter and Paul Cathedral (Russian: Петропавловский собор) is a Russian Orthodox cathedral located inside the Peter and Paul Fortress in St. Petersburg, Russia.

Both the cathedral and the fortress were originally built under Peter the Great and designed by Domenico Trezzini. The cathedral's bell tower is the world's tallest Orthodox bell tower. Since the belfry is not standalone, but an integral part of the main building, the cathedral is sometimes considered the highest Orthodox Church in the world.
