Here’s a great way to jazz up a spring weekend: check out Doors Open Denver, a FREE, two-day event that’ll let you get an expert look at the architecture of Denver’s most interesting buildings.

You can take guided tours of historic and outrageously contemporary places — many of which are not usually open to the public — or walk through several neighborhoods. This free, annual event is worth adding to your calendar.

Doors Open Denver is sponsored by the Denver Architectural Foundation to celebrate the city’s unique architectural landscape. Each year, thousands of attendees tour Denver’s prominent architectural treasures, including civic buildings, mansions, hotels, museums, churches and schools.
