One of St. Petersburg's most famous and popular visitor attractions, the palace and park at Peterhof (also known as Petrodvorets) are often referred to as "the Russian Versailles", although many visitors conclude that the comparison does a disservice to the grandeur and scope of this majestic estate. Versailles was, however, the inspiration for Peter the Great's desire to build an imperial palace in the suburbs of his new city and, after an aborted attempt at Strelna, Peterhof - which means "Peter's Court" in German - became the site for the Tsar's Monplaisir Palace, and then of the original Grand Palace. The estate was equally popular with Peter's daughter, Empress Elizabeth, who ordered the expansion of the Grand Palace and greatly extended the park and the famous system of fountains, including the truly spectacular Grand Cascade. Improvements to the park continued throughout the 18th and 19th centuries. Catherine the Great, after leaving her own mark on the park, moved the court to Pushkin, but Peterhof once again became the official Imperial Residence in the reign of Nicholas I, who ordered the building of the modest Cottage Palace in 1826. Like almost all St. Petersburg's suburban estates, Peterhof was ravaged by German troops during the Second World War. It was, however, one of the first to be resurrected and, thanks to the work of military engineers as well as over 1,000 volunteers, the Lower Park opened to the public in 1945 and the facades of the Grand Palace were restored in 1952. The name was also de-Germanicized in 1944, becoming Petrodvorets, the name under which the surrounding town is still known. The palace and park are once again known as Peterhof.

This Church was built on the site where Emperor Alexander II was severely wounded and died in March 1881.The church was built from 1883 till 1907. The construction was funded by the imperial family. Architecturally, the Cathedral differs from St. Petersburg's other structures. The Church contains over 7500 square meters of mosaics—according to its restorers, more than any other church in the world. The walls and ceilings inside the Church are completely covered in intricately detailed mosaics — the main pictures being biblical scenes or figures — but with very fine patterned borders setting off each picture.

Although it is only a 20th century creation, Palace Bridge is undoubtedly one of the most famous sights of St. Petersburg, and is quite literally unmissable for most visitors to the city, who will find themselves continually using the bridge to move between Palace Square, home to the Winter Palace and the Hermitage Museum, and the numerous historic attractions on Vasilevskiy Ostrov. Despite the grandeur and extravagance of the surrounding architecture, Palace Bridge itself is a relatively simple structure, comprising five cast-iron spans resting on granite-clad, packed-rubble piers. Height of the bridge was strictly limited, so as not to obstruct the view of the monuments around. The central span of the bridge splits into two wings, which are raised through an angle of over 45° to allow ships to pass up the Neva River, and the view of the golden spire of the Ss. Peter and Paul Cathedral between the two raised wings is one of the most widespread and memorable images of St. Petersburg. It also makes Palace Embankment the centre of nightly celebrations during the White Nights, when thousands of locals and visitors gather to watch Palace Bridge open in the small hours.
