Abstract: Since the demolition of the walls of the ancient city of Taiguin Shanxi Province， the spatial pattern of the whole city has been destroyed in an unprecedented manner， and the traditional street and alley patterns and some architectural remains have become the last historical remains of the ancient city， which continue the urban pulse of the old Taigu and carry the unique regional spirit of the Jinzhong region. Starting from an overview of the traditional streets， an in-depth study of the traditional street pattern within the historical and cultural district is carried out by analyzing the road network structure， street scale and street names， and proposing research strategies for the renewal and protection of the street pattern， in order to provide reference for the renewal and protection of other traditional streets and alleys.

Key words: historical and cultural blocks, street and lane pattern, renewal of the ancient city, Taigu ancient city
