Patapsco Flour Mill

Closed in 2021, this site — formally known as the Wilkins-Rogers Mills — was the last of many that turned Ellicot City into a milling town during the Industrial Revolution. Today, the building is still accessible from the street. There is a corrugated metal overhang that you can easily crawl under. External fire escapes and broken windows provide access to the full interior, though I haven’t tried entering myself. 

Directions

The mill is located at 27 Frederick Road in Ellicot City, MD. You can park across the street at Old Mill Cafe. While you’re there, be sure to check out the Temple of the Dragon, which is within driving distance and much cooler.
