Though Lowertown St. Paul has undergone a remarkable renaissance in recent years, it wasn’t long ago that the area was a ghost town of parking lots and vacant structures. During those years, however, the St. Paul Art Collective made Lowertown its home, building a thriving network of studios within local warehouses. The creative flourishing that followed resulted in the Saint Paul Art Crawl, a tradition that has overgrown its original borders to encompass an enormous portion of the city. The vast setting is necessitated by the 300-plus participating artists, as well as more than 20,000 attendees converging on the city over the weekend. In addition to exhibitions and installations of countless disciplines and styles, the festival features an intriguing range of performance arts, interactive tutorials, and guided studio tours. While such a dizzying array of options can present an organizational challenge to visitors, the Collective has thoughtfully posted an exhaustive guide on www.saintpaulartcrawl.org, and arranged for complimentary transportation via MetroTransit.
