Architectural heritage is an important cultural resource in the city, and its macroscopic spatial pattern and accessibility are important for the conservation of architectural heritage and the development of heritage tourism. This paper explores the spatial pattern and accessibility of architectural heritage in Chengdu by using spatial analysis of 308 declared national, provincial, and municipal cultural relic protection units in Chengdu as the object of architectural heritage research. The results showed that: (1) The distribution of architectural heritage was generally clustered, and the clustering areas of various types of architectural heritage differ significantly, with architectural heritage mainly concentrated in the central urban areas; (2) The integration value of various road networks connecting architectural heritage in the central urban area were significantly better than those in other areas; (3) The transportation accessibility index of architectural heritage in the central urban areas was higher, while the transportation accessibility index of architectural heritage in the surrounding areas was lower.
