Excursion walks around Petropavlovsk.

“From the cathedral I went to the house of the merchant Smolin, where there was a guard of honor from the local team; then he went to the consecration of the newly completed building of the city school and after the prayer service he returned to the same house of Smolin, who treated him to a magnificent breakfast and a lot of wines, among other things, and honey.”

Diary of Tsarevich Nikolai Alexandrovich, future Tsar Nicholas II, July 31, 1891.

Architectural sights of Petropavlovsk.

The house of the Smolin merchants was located at an altitude of 129 meters above sea level, located in the southern part of Pushkinskaya Street, 73 between Buketova and International streets, in the central part of the city of Petropavlovsk. 
The two-story house of the Smolin merchants was built in 1874. Warehouses and storehouses located in the courtyard served as a place for merchants to conduct retail trade in flour and wholesale trade in wine and vodka products.
In 1916, a branch of the Siberian Commercial and Industrial Bank was added to the main building. The main buildings have several extensions erected to increase the area of utility and utility rooms. As a result, the facades of the northwestern side of the building adjacent to Bankovskaya (now Sovetskaya) street were completely hidden by the walls of the buildings that formed the courtyard.
Thus, several separate buildings were connected into a single whole. The walls of the main building (built in 1874) were built from poorly fired bricks of poor quality. As a result, by 2002, the main building fell into disrepair and was demolished.
The remaining buildings of later buildings, erected in the architectural style of the main building, have been restored and are used in economic and commercial activities. The storage sheds and outbuildings in the courtyard have also undergone major repairs and restoration and are currently used to house production and storage facilities.
Their walls are decorated with intricate figured masonry along the pediment. The facades that have survived from earlier buildings are rich in relief brickwork with ornaments characteristic of the so-called “Russian style”, which became widespread in the Siberian lands at the beginning of the twentieth century.
During Soviet times, two memorial plaques were installed on the building. The first one had the inscription: “In the city of Petropavlovsk in November 1919 there was the headquarters of the 5th Red Army under the command of M.N. Tukhachevsky."
On the second: “In this building in November 1919, the Czech communist writer Jaroslav Hasek worked in the political department of the headquarters of the 5th Red Army.” Today there are no memorial plaques. 
5th Red Army under the command of M.N. Tukhachevsky (the operational combined arms formation (army) of the Workers' and Peasants' Red Army of the Armed Forces of Soviet Russia during the Civil War and intervention in Russia (1918 - 1922) liberated the city of Petropavlovsk from the Kolchakites.
The world famous Czech writer Jaroslav Hasek was part of the army. In honor In one of the modern northern districts of the city, a street is named after him. One of the city streets is also named after Tukhachevsky.
In Soviet times, these buildings housed the educational and production buildings of State Pedagogical Technical University - 25. On October 25, 2004, in Petropavlovsk, the main building of the merchant Smolin’s house, which stood at the intersection of Pushkin and Buketov streets, was dismantled.

Historical information about Smolin family. 
Hereditary honorary citizen Dmitry Ivanovich Smolin was born in 1833 into a family of Yalutorovsky 3rd guild of merchants in the city of Yalutorovsk, Yalutorovsk district, Tobolsk province, West Siberian Governor-General, now the city is the administrative center of the Yalutorovsky district of the Tyumen region.
He graduated from the Yalutorovsky district school, perhaps he studied at the Lancaster school of I. D. Yakushkin. After graduating from the Yalutorovsky district school, he received an inheritance of 4,000,000 rubles and began independent commercial activity.
This is a short start. DI. Smolin was widely known in Siberia. He was an Honorary Member of the Tobolsk Provincial Trusteeship of Children's Shelters, a member of the Society for the Care of wounded, established in Omsk, member of the Paris National Academy, director of the Kurgan Trusteeship Society for Prisons, chairman of the committee for the analysis and charity of the poor in Kurgan, Honorary Citizen of Petropavlovsk and Kurgan, church warden of the Trinity Cathedral.
His important merit was that he put Siberian lard and Siberian melted butter on stream. He was the first to establish the sale of oil abroad to southern ports for export to Turkey. And he did this 20 years before the organization of the Union of Siberian butter-making artels A.N. Balakshina.
The house belonged to Sergei Smolin, the brother of Dmitry Smolin. The latter was engaged in flour grinding, distilling, lard heating, agriculture and other things. He came from the Yalutorov merchants of the third guild, lived and did business in Kurgan.
The house was inherited in 1887 by brother S.I. Smolin to Dmitry Ivanovich, and then to the eldest son - Alexander Dmitrievich Smolin - Peter and Paul merchant of the 2nd guild. Alexander Smolin, was born into the family of Kurgan merchant Dmitry Ivanovich and Elizaveta Fedorovna Smolin on September 27, 1869.
In 1897 he settled in Petropavlovsk, because he did not yet have his own house in Kurgan, but in Petropavlovsk the Smolin family had estates and trade. From Vasilyeva’s book “Kurgan Merchants” we read: “Soon after his marriage, brother Sergei and sister Elizaveta come to live with Dmitry Ivanovich.
On February 4, 1862, he married his sister to Alexander Nezgovorov, his brother Sergei leaves for Petropavlovsk, opens a trade and becomes a 2nd guild merchant, but constantly comes to Kurgan and stays here for a long time.”
In addition to Sergei Smolin, Alexander Smolin (son of Dmitry Smolin) and his family also lived in Petropavlovsk. Thus, Alexander and his wife Natalya Oshurkova lived in Petropavlovsk for some time after their marriage, since they did not yet have their own home in Kurgan.
Here the Smolins had estates, inherited from Sergei Ivanovich Smolin, and trade. In Petropavlovsk, on July 17, 1898, the couple’s eldest daughter, Elizaveta, was born. She was baptized in the local Ascension Cathedral.
Probably daughters Nina and Olga were born here. After the death of Dmitry Ivanovich Smolin, according to the separation act of 1902 between the heirs of Dmitry Ivanovich, the Peter and Paul estate was also given to Alexander - the former estates of Sergei Smolin, inherited in 1887 by his brother Dmitry, a one-story wooden house with an outbuilding in the village of Kokchetavskaya, Akmola region, two houses in Petropavlovsk, on the flour market, a half-stone two-story house, a stone tent with outbuildings and a manor.
And in the first building of the Gostiny Dvor retail shops there is a walk-through stone shop. In Petropavlovsk, Alexander Dmitrievich was listed as a merchant of the 2nd guild, was an Honorary Superintendent of the Petropavlovsk Five-Class City School and a member of the Board of Trustees of the Women's Gymnasium.
He was actively involved in charity work and public education. Died in 1921.
