The concrete was never grey.
Forty years after the formwork came off, the slabs of New Belgrade are read as failure. Walk Block 23 on a Tuesday in March and a different argument forms itself.
The first time I walked through Block 23, in the winter of 2019, the wind off the Sava was loud enough that I had to read the building from arm's length. Eight stories of formwork-traced concrete, banded in horizontal scoring marks where the carpenters had reset the boards. The orange of the playground equipment, repainted that autumn, was the only loud thing for half a kilometre.
I had come, ostensibly, to write about decline. The Western press had spent a decade describing these blocks as monuments to a failed century — heavy, brutal, joyless. I had been hired to confirm it. Instead I spent two weeks with a thermos and a notebook, watching the geometry do its quiet daily work: children to the courtyard at four, pensioners to the south-facing benches at five, the trams threading the spine of the avenue every six minutes on the dot.
EXAT-51 understood what we forgot
The architects who drew these slabs were not, as is now fashionable to claim, ideologues with rulers. They were students of EXAT-51 — a group that in 1951 argued, against the official line, for the right of abstraction to coexist with social purpose. They built circles into the playgrounds and teal grids into the signage because they believed geometry was for everyone, not only the museum.
