Hortus conclusus is an enclosed garden behind a wall, a frequent subject of medieval and Renaissance painting. Gütschow finds such gardens in the city: instead of a wall, concrete grilles, old brick and graffiti; instead of a garden, a lawn with a couple of trees amid asphalt and paving stones.
Each image is assembled from more than 150 photographs of a single place. Software stitches them into a three-dimensional model, and Gütschow turns it into a cavalier perspective. That is why the lines in the pictures run parallel and never converge, and cubes turn into rhombuses.
