Sassenpoort
Look closely at the walls of the Sassenpoort and you will see dimension stone, specifically trachyte and tuff. This Gothic city gate was started in 1406 and built in 1409. Jacobus van Lokhorst was the architect for this structure, which stands as a gatehouse in the city wall of Zwolle, the Netherlands. It is a rijksmonument and is recognized as part of the Top 100 Dutch heritage sites. While the stone has stood for centuries, the gate underwent restoration work between 1893 and 1898 to keep it in good shape. I've seen many things from the air while gliding over the city, but the scale of this gate always catches my eye. It is a wonderful spot to stop and appreciate the craftsmanship of the past.
