The escarpment is what sets this map apart from flatter cities like Berlin or Amsterdam. Stand on the castle terrace or at the top of the Old Town stairs and the river, the boulevards and the whole Praga bank are laid out below you. The drop is there in the world, about 25 blocks from Castle Square to the water, so streets like Bednarska and Karowa wind down it. It makes the city easy to read: the Old Town and the center are up, Powiśle and the river are down, and the Poniatowski Bridge runs out from the top of the slope on a long viaduct.
Within about 2.5 km the city changes era several times. The Market Square, Krakowskie Przedmieście, the Palace of Culture and Varso Tower are all that close to each other, and the street plan changes with each: medieval lanes in the Old Town, a long royal avenue, wide postwar axes around Plac Defilad, and the courtyard blocks of Praga. For builders this is a good test map, because each district needs a different palette and roof style to finish.
Building shapes come from footprints with flat roofs, so the castle’s clock tower, the Barbican’s turrets, the church spires and the decorated Old Town gables are not there. Tall buildings that are mapped in parts do better: the Palace of Culture rises in stepped tiers, but without its clock faces, corner pinnacles or carved detail. Statues, including Sigismund’s Column, the Mermaid and the Chopin Monument, appear as small footprints at most. The metro is underground and not generated, and building interiors are empty. What you do get is the real street plan, the real escarpment and river, and every mapped building on its real footprint, most of them at roughly the right height.
