Are you a person that enjoys finding out how and why things were built the way they were?  Doors Open Denver is an analysis of architecture of the 1950′s and beyond all over Denver.  In Northwest Denver, several of the buildings on the Regis University campus are studied through free walking tours (the Adult Learning Center, Field House, Loyola Hall, Pomponio Science Center, and the St. John Francis Chapel).   Also on the tour schedule in the neighborhood: Olinger Moore Howard Chapel, the Millennium Bridge, and the REI Flagship store.  To find out more information on this great event and where else in the city to venture, visit the cities website at: http://denvergov.org/doca/DenverOfficeofCulturalAffairs/DoorsOpenDenver/tabid/440781/Default.aspx.
