Despite abundant scholarship on religious architecture and urban history, a systematic city-wide analysis that treats the parish system as a territorially relevant infrastructure for planning remains uncommon. This article examines Barcelona’s network of 132 Catholic parish churches as a cartographic layer for interpreting distributed centralities and their relationships with public space. The study is grounded in an exhaustive inventory based on on-site visits and archival consultation, and on a standardised redrawing protocol (Sitte and Nolli conventions) developed from municipal cartography and architectural plans. Synthesis maps and fabric-specific drawings document spatial patterns that vary across phases of urban growth, as well as recurrent typologies of relationships between churches, squares, and urban axes. Across the corpus, at least 25 churches are associated with squares and can be grouped into four recurrent arrangements (12 with a single frontal square; 4 with concatenated lateral squares; 3 surrounded by open space; and 6 with squares severed by through-traffic infrastructure). District plates further reveal contrasting typological distributions between Ciutat Vella (n = 16), Eixample (n = 19), Gràcia (n = 11), and Nou Barris (n = 14). The findings show that Barcelona’s Catholic parish cartography constitutes a key interpretative layer for understanding the city’s complexity, including its social and urban transformations, neighbourhood-level mechanisms of resilience, and the interaction between religious networks, urban form, and civic culture. The resulting cartographic protocol is reproducible and transferable to studies of urbanisation and regional development, offering an operational framework for planning debates on the governance of public space, heritage conservation, and urban sustainability.
