Saint Isaac's Square or Isaakiyevskaya Ploshchad (Russian: Исаа́киевская пло́щадь), known as Vorovsky Square (Russian: Площадь Воровского) between 1923 and 1944, in Saint Petersburg, Russia is a major city square sprawling between the Mariinsky Palace and Saint Isaac's Cathedral, which separates it from Senate Square. The square is graced by the equestrian Monument to Nicholas I. The Lobanov-Rostovsky House (1817–20) on the west side of the square was designed by Auguste de Montferrand. It may be described as an Empire style building that has an eight-column portico facing the Admiralty building. The main porch features the twin statues of Medici lions on granite pedestals; they were made famous by Pushkin in his last long poem, The Bronze Horseman. Nearby is Quarenghi's Horse Guards' Riding Hall (1804–07), in part inspired by the Parthenon and flanked by the marble statues of the Dioscuri, by Paolo Triscornia. Opposite the cathedral is the Mariinsky Palace, built in 1829-1844 for Grand Duchess Maria Nikolayevna. Currently the palace houses the Saint Petersburg Legislative Assembly. In front of the palace is the 97-metre-wide Blue Bridge, which used to be the widest in Saint Petersburg. Spanning the Moika River, the bridge is usually perceived as the extension of the square, although in fact it forms a separate square, called Mariyinskaya. To the right from the bridge is so-called Neptune's Scale, with a granite top. This is a stele which marks water levels during major floods. To the east of the cathedral is the six-storey Hotel Astoria, designed by Fyodor Lidval. It opened in 1912 and was one of the most luxurious hotels in the Russian Empire. Adjacent to the Astoria is the hotel Angleterre, which is remembered as the deathplace of poet Sergei Yesenin. The building found at the corner of Malaya Morskaya Street is associated with Fyodor Dostoyevsky, who lived there in 1848-1849. At this period, he published his first work of fiction, White Nights. The Russian Institute of Plant Breeding named after Academician Nikolai Vavilov is located in two neo-Renaissance buildings. The institute has a unique collection of 160,000 cultivated plants, which Vavilov collected while travelling in every continent from 1921 to 1940. After the end of the war, a journal published in London reported that Vavilov's collection was lost during the Siege of Leningrad. However, the report was false: although many starved to death, the institute's staff would not consume a single grain of rice or potato tuber from the collection.One of the last buildings to be erected on the square was the trapezoidal red-granite German Embassy (1911–12), by the architect Peter Behrens. The building is a reference point in the history of Western architecture, as it was the first specimen of Stripped Classicism, a style that enjoyed immense popularity in Stalinist Russia and Nazi Germany.

The Monument to Nicholas I (Russian: Памятник Николаю I) is a bronze equestrian monument of Nicholas I of Russia on St Isaac's Square (in front of Saint Isaac's Cathedral) in Saint Petersburg, Russia. It was created by French sculptor Auguste de Montferrand and unveiled on July 7 [O.S. June 25] , 1859, the six-meter statue was considered a technical wonder at the time of its creation. It is one of only a few bronze statues with only two support points (the rear hooves of the horse).

The Blue Bridge (Russian: Си́ний мост, Siniy most), is a 97.3-metre-wide (319 ft) bridge that spans the Moika River in Saint Petersburg, Russia. The Blue Bridge is the widest bridge in Saint Petersburg and is sometimes claimed to be the widest bridge in the world – a claim, however, that has not been recognized by international reference works, such as the Guinness World Records. The Blue Bridge spans the Moika River and is located in front of the Mariinsky Palace at Saint Isaac's Square in city's historic centre. The first cast iron bridge on the site was designed in 1805 by the architect William Heste, and built in 1818. This bridge was a single-span bridge resting on stone supports, and measured 41 metres across. In 1842–1844, the bridge was widened on its northern side to its present width of 97.3 metres - just as wide as the adjacent Isaac's Square. Soon after the bridge was widened, there were rumours that the new width of the bridge was 99.9 metres instead of the actual 97.3. This rumour even made it into some official booklets and textbooks. Today, most of the Blue Bridge serves as a parking lot. The bridge's name dates from a 19th-century tradition of color-coding the bridges crossing the Moika River. Like other colored bridges, the Blue Bridge got its name from the color of its sides facing the river. Today only four colored bridges survive, the other ones being the Red Bridge, the Green Bridge and the Yellow Bridge respectively. Three of them kept their original names, while Yellow Bridge has been renamed to Pevchesky Bridge.

The former Embassy of Germany in Saint Petersburg is considered the earliest and most influential example of Stripped Classicism. It was built to house the diplomatic mission of the German Empire in Saint Petersburg, the capital of the Russian Empire. After the relocation by the Bolsheviks of the Soviet capital from Petrograd (as Saint Petersburg was then known) to Moscow, it served as a consulate of the Weimar Republic and Nazi Germany. Located at 11/41 Saint Isaac's Square (Russian: Исаакиевская площадь, дом 11/41) in the Tsentralny District of Saint Petersburg, the building now houses the offices of two Russian government agencies.

Lobanov-Rostovsky Residence or the Lobanov-Rostovsky Palace is a building at 12 Admiralteysky Avenue in Saint Petersburg, Russia, constructed in 1817-1820 for Prince Alexander Yakovlevich Lobanov-Rostovsky. Today, the building houses a luxury hotel in the Four Seasons Hotels and Resorts chain, under the name of Four Seasons Hotel Lion Palace, referring to the two Medici Lions at the main entrance. It is not to be confused with the Lobanov-Rostovsky House at 43, Myasnitskaya Street, Moscow.

Voznesensky Prospekt (Russian: Вознесенский проспект) is a 1.8 km long street in Admiralteysky District of Saint Petersburg, Russia. Crossing Saint Isaac's Square, the Moika (Blue Bridge) and Griboyedov Canal (Voznesensky Bridge), the street spans from Admiralteysky Prospekt to Izmaylovsky Bridge across Fontanka, where it turns into Izmaylovsky Prospekt. According to the city plan of 1737, the center of Saint Petersburg should develop along three radial axes meeting at the Admiralty's spire: Nevsky Prospekt, Gorokhovaya Street and Voznesensky Prospekt. In 1923-1991 the street was named Mayorov Prospekt (Проспект Майорова) after a prominent Bolshevik killed in the Russian Civil War.

Saint Isaac's Cathedral or Isaakievskiy Sobor (Russian: Исаа́киевский Собо́р) is a large architectural landmark cathedral that currently functions as a museum with occasional church services in Saint Petersburg, Russia. It is dedicated to Saint Isaac of Dalmatia, a patron saint of Peter the Great, who had been born on the feast day of that saint. It was originally built as a cathedral but was turned into a museum by the Soviet government in 1931 and has remained a museum ever since, with church services held in a side chapel since the 1990's. In 2017, the Governor of Saint Petersburg offered to transfer the cathedral back to the Russian Orthodox Church, but this was not accomplished due to the protests of St Petersburg citizens opposing the offer.
