Doors Open Denver 2011 will take place the weekend of April 16 and 17.  Residents and visitors will have the opportunity to experience Denver’s built environment in a special way—from inside many buildings that are not ordinarily open to the public.  Attendees will have access to more than 70 of Denver’s prominent architectural gems and lesser-known treasures.  These include corporate offices, mansions, architecture and design studios, hotels, commercial and retail buildings, museums, educational facilities and more.  Note that about half of the sites to be featured in 2011 are new to Doors Open Denver. 

Doors Open Denver is a FREE event.  Hours will be 10:00 am – 4:00 pm on Saturday and Sunday.  Event headquarters will be located inside Union Station, 1701 Wynkoop.

Expert Tour participants must pre-register at event headquarters on the tour day to reserve a place.  Tours have limited capacity, but many tours will be offered more than once.  Registration will be available on a first-come, first-served basis.  Only two tickets per person and two tours per day/per person will be permitted.  Only those wishing to take expert tours need to come to event headquarters.  Self-guided experiences can start at any participating location.
