Utrecht has a long history of silversmiths, dating back hundreds of years. One of the more recent silversmith families was the Brom Brothers, who had a foundry on Keizerstraat. The foundry is no more, but the chimney (schoorsteen) remains and is a favorite of mine to photograph when the sky is blue and bright.
If you know more about this history of the building/chimney, please let me know. I’m always interested to learn more!
