I've always wanted to check out some of these things. Maybe an Expert Tour?
Doors Open Denver will celebrate the local architects that have shaped Denver during a FREE two-day event that allows you to go behind the scenes of the city’s significant architectural gems and lesser-known treasures.
Saturday, April 18 and Sunday, April 19 10 a.m. to 4 p.m.
Spend the day on a self-guided tour of both historic and modern buildings, register for an Expert Tour or embark on an Urban Adventure - a self-guided tour based on a theme.
Check out the list of participating sites, Expert Tours, Urban Adventures and special activities on the Doors Open Denver website.
