Petrine Baroque (Rus. Петровское барокко) is a style of 17th and 18th century Baroque architecture and decoration favoured by Peter the Great and employed to design buildings in the newly founded Russian capital, Saint Petersburg, under this monarch and his immediate successors. 
Different from contemporary Naryshkin Baroque, favoured in Moscow, the Petrine Baroque represented a dramatic departure from Byzantine traditions that had dominated Russian architecture for almost a millennium. Its chief practitioners - Domenico Trezzini, Andreas Schlüter, and Mikhail Zemtsov - drew inspiration from a rather modest Dutch, Danish, and Swedish architecture of the time.

Extant examples of the style in St Petersburg are the Peter and Paul Cathedral (Trezzini), the Twelve Colleges (Trezzini), the Kunstkamera (Mattarnovi), Kikin Hall (Schlüter) and Menshikov Palace (Giovanni Fontana).
Architectural influences on Peter the Great
Peter the Great, also known as Peter I, served as the tsar of Russia from 1682-1725. He was the first Russian monarch to travel outside of Russia and this travel exposed him to the architecture of many other countries. His own library contained architectural books from the Netherlands, France, Germany and Italy. The buildings of these countries influenced Peter's taste in architecture as he set forward to build the new Russian capital of St. Petersburg. Peter had a very specific idea of what he wanted this new city to look like in terms of architectural style, and he took initiative in recruiting people who could help accomplish his vision and researching architectural styles. While in rule, Peter attempted to bring about change to the nation of Russia as quickly as possible and tried to incorporate western style and tradition into the everyday lives of his citizens. As part of this, Peter put regulations into effect which mandated what cities should look like. Peter's original goal for St. Petersburg was to re-create the city of Amsterdam. As the city began construction, Peter started making changes to the designs of the buildings, often altering the planned appearance of buildings once their construction had already started. These last minute alterations led to buildings not belonging to one particular architectural school.
Naryshkin Baroque style
Peter was raised in Moscow, lived at the Grand Palace of Kremlin, and spent time at multiple royal estates outside of the city. His father died when he was four years old, so Peter had a fairly unsupervised youth to pursue his own passions. Peter developed his taste for architecture by looking at the buildings which surrounded him in his childhood, many of which were patronized by his family. These churches and houses which surrounded Moscow reflected European influence in their structure and decoration. The Moscow or Naryshkin Baroque style, named after Peter's maternal side of the family, was prominent in these buildings. Characteristic of the Naryshkin Baroque style is large scale buildings and lack of wood amongst building materials.
Dutch Baroque style
As Peter entered young adulthood and spent time travelling, his architectural taste began to favor the elements of Dutch architecture. Peter met with the Dutch architect Simon Schijnvoet (sometimes Schynvoet or Schynvaet) in 1697. Schijnvoet specialized in Dutch Baroque but also taught Peter about naval architecture. The first house in St. Petersburg that Peter designed utilized elements from this naval style which Schjinvoet taught him, including flat, painted log walls, wooden tile-like shingles, and windows made from small planes of glass. These elements of design were unlike the Russian styles seen up until this point. The Russian history scholar James Cracraft suggests that the clearest example of Dutch architecture designed under Peter's rule was his Summer Palace in St. Petersburg which was referred to as "Monplaisir" or "Little Dutch House". In a 1724 letter to the architectural student Ivan Korobov, Peter discusses his preference for the ornamentation of Dutch Baroque. In this same letter, Peter conveys his disinterest for the architectural styles of the French and Italian due to its lack of adornment and use of stone rather than brick. Among Peter's papers, a note was found describing how he sent two Russian architecture students to Holland so that they could learn the Dutch Baroque style and come back to build churches and houses for St. Petersburg. In addition to having Russian students train abroad, Peter also hired Dutch architects to come and work on projects in Russia.
While Peter preferred the Dutch Baroque style, he also sought out architectural inspiration from other countries. Despite his recorded dislike for the French and Italian styles, Peter sent two architectural students to Rome in 1723 to replace another two students working there. Scholars suggest that an equal amount of architectural students were sent to Holland and Italy during his reign and more Italian builders worked on projects for Peter in Russia than Dutch builders did. In the early years of St. Petersburg, the French served as prominent designers and decorators.
Domenico Trezzini was born in Italian controlled region of Switzerland in 1670. The architects that surrounded him in his youth were responsible for the development of the Baroque style in southern Germany. Trezzini's architectural style has visible influences from this German Baroque style along with the northern style of Baroque architecture that he picked up during his time living in Copenhagen. Trezzini was also influenced by the Lombard Baroque style of architecture which was popular in Northern Italy where he grew up during the 17th century. From 1703 until his death in 1734, Trezzini lived in St. Petersburg during the rule of Peter the Great. Trezzini began many of the building projects that formed the basis of the city. Due to the many projects that Trezzini worked on, he was given the title of "Lieutenant-Colonel of Fortification and Architect" in 1710.
Some of Trezzini's major additions to the city include: Peter the Great's Summer Palace, the Alexander-Nevskii Monastery, the Twelve Colleges, and the Peter-Paul Church. Trezzini and his team designed the layout of the developing St. Petersburg including the streets of the anticipated city center of Vasilyevsky Island. The layout of the city was arranged in a grid format with perpendicular streets and canals. Trezzini's design of the city did not follow the European ideal at the time because of its lack of compactness and grid organization rather than the traditional ringed layout.
In 1714, Peter declared that all houses in St. Petersburg should be constructed after Trezzini's model home. Different versions of the home were created for different classes of citizens based on their rank. Peter classified all citizens into 14 different classes, all of which had different residential areas in Trezzini plan. The size of the citizen's home directly corresponded to their standing in this social ranking. The lower classes were divided by their trades and the upper classes were divided by the amount of serfs that they controlled. Several engravings of the model homes exist and while they are often accredited to Trezzini himself, his assistant Jean-Baptiste Alexandre Le Blond is responsible for creating them. These plans dictated the ornamentation style of the homes and the materials that they would be built with belonging to each class of citizens. In the city center proper, these guidelines were adhered to strictly. The further from the city center, the more flexibility with the design of homes there was. Despite the effort put into maintaining a regulated city design, after Peter's death, the system that Trezzini designed fell to the wayside. Scholars consider Peter I's comprehensive urban design to be one of his greatest legacies.
In the design of his buildings, the Dutch Baroque style is visible in the types of ornamentation he preferred. For columns, Trezzini preferred squared pilasters as a decorative element and restricted their use to where they were structurally necessary or served a major purpose in the overall design. Trezzini also took inspiration from the work of Christopher Wren, whose work on the St. Paul's Cathedral appears in Trezzini's sketches.
Trezzini established the St. Petersburg Chancellery of Construction and became its first director. This school was the first institution to offer formal training for architects in Russia. Among those who trained at the Chancellery was Mikhail Zemtsov who continued Trezzini's legacy. Other architects whom Trezzini worked alongside during his life and continued the construction of his buildings after his death were Carlo Giuseppe and Pietro Antonio Trezzini.
