>>1297157Interestingly, the Barcelona street grid you posted was designed with octagonal blocks, with "cut off" edges to allow trams, or "domesticated engines" as its designer Ildefons Cerdà envisioned it in 1859. This is a fact barely known by Barcelona's residents themselves, who instead have made up all kinds of silly theories on why the edges are cut off, ranging from visibility to street parking space (in 1859, my fucking sides).
Yet despite that, Barcelona never had a particularly extensive tram system, with relatively few lines within the grid area.
