Thanks to Doors open Denver, anyone in town the weekend of April 12 has the opportunity to get up close and personal to some of the city's most interesting buildings. For the third straight year, eighty of Denver's most significant structures will open their doors to visitors all weekend. The event offers a plethora of ways to explore the participating buildings, ranging from informative group tours to family-friendly activities.

This year there are 28 expert-led tours throughout the weekend and participants will have the chance to listen in as historians and architects share their knowledge of places like the Civic Center in Golden Triangle and the Highland Masonic Center. But, if you're like me and walking around with a bunch of strangers doesn't do it for you, grab an event guide and set off on a self-guided tour.
