Around 9:00 tonight Rosenwach Tanks (makers of the ubiquitous rooftop water tanks) caught on fire. It was an intense fire, and an hour later flames could still be seen leaping up from the building at the corner of North 9th and Wythe. A lot of fire trucks were on scene, along with police for crowd control. There aren’t a lot of buildings on the property, but there is a lot of wood stored there.
