Like we secure our bikes to the bridge railings outside, Navid Nuur locks his art to the Oude Kerk. The shapes of these locks echo the wrought ironwork of Amsterdam’s inner-city bridges. Architect Piet Kramer designed nearly all these bridges up until 1952, with local artisans executing the wrought ironwork. Nuur’s locks speculate on the retention and forgetting of knowledge, the transformation of materials from raw to final form, and the church as a structure of makers interconnected across time.
