May is National Historic Preservation Month.
Denver is filled with a lot of history.
You can see a lot of it - in its architecture.
The organization Historic Denver is holding a photo contest all month to mark the 50th anniversary of Denver's Landmark Preservation Program.
It's asking everyone, from amateurs to professional photographers, to snap photos of their favorite historic places - whether it's officially a landmark or not.
To officially submit photos you must email them to this address, email@example.com.
A panel of Historic Denver board members will select the Grand Prize Winner, and two runners-up to receive gift cards to local establishments, publication in the organization's print newsletter, and promotion on social media.

And of course, if you just want to share your favorite historic places you can post them on your social media pages with #beHistoricDenver.
Historic Denver will repost submissions shared with that hashtag on its social media platforms.
Fans and followers can "like" submissions, and the post with the most likes will receive the fan favorite award and a prize.
Historic Denver, Inc. was founded in 1970 through a chain of events that spurred a group of passionate citizens to prevent demolition of the 1889 home of Titanic survivor Margaret "Molly" Brown. The home became the Molly Brown House Museum, which the organization continues to operate today.
