This is the basic study about urban history of Far East Russia. This paper aims to clarify the formation of block pattern around former Semenovsky Bazar in Vladivostok, from three points of view such as block pattern, land lot and urban unit. Block pattern and land lot pattern were made by 1870's. The development of urban unit was seen by 1880's at first, and it means dividing a land lot to rent tiny ones by land owners. Building construction became more active from around 1900 to middle of 1910's and it made urban unit more various and facade of buildings more united. This form has been partly destroyed since 1960's by the authority's policy because of decrepitude of tiny buildings.
