About Doors Open Baltimore

Baltimore Architecture Foundation’s city-wide celebration of architecture, “Doors Open Baltimore,” draws thousands of participants to explore Baltimore neighborhoods, engage with cultural sites, and change perceptions of Baltimore for the better. It is an annual celebration of civic pride and a way for buildings, which normally recede into the background of our everyday lives, to take center stage. 

Doors Open Baltimore is for everyone – regardless of age, race, gender, ability, education, or architectural expertise. Offering experiences and encouraging dialogue about architecture and urban design creates awareness that the public has a stake in the design, development, and care of its city.

My family had a wonderful time in this museum! It’s the perfect balance of visually appealing and interactive for my boys (ages 5 & 8). We would definitely go again!
