Museum Weverij De Ploeg in Bergeijk

You're standing at Weverij de Ploeg, a former weaving mill in Bergeijk. Start with the roof. That row of wavy concrete arches is this building's signature. There are eight curved shed roofs, four long and four short, and they're only seven centimetres thick. In the nineteen-fifties, that was pushing the limits of what concrete could do.
