Denver's premier independent creative-writing institution, Lighthouse Writers Workshop, announced its new location this week, a brand-new building at 39th and York streets, just off the new greenway bordering the Clayton and Cole neighborhoods. Lighthouse had previously done business — and offered important literary contributions to the city and state — at various historic sites. Early on, the group founded in 1997 operated out of the Thomas Hornsby Ferril House, named for Colorado’s first poet laureate. Most recently, the nonprofit has been based in the equally historic Milheim House, which was moved from 1355 Pennsylvania Street (across from the Molly Brown House) to1515 Race Street in 1989.
