Doors Open 2011 has come and gone, leaving behind an array of photographs of the various participating venues. As was to be expected, the R.C. Harris Water Treatment Plant proved one of the most popular destinations, a fact out by the remarkable photographs we get to pore over today. Our site-specific Doors Open coverage this year focused on some of the buildings that we had yet to visit or see many photographs of, but because there's just so much cool stuff on offer, this photo gallery from the blogTO Flickr pool aims to give a general sense of what the weekend was like. It still, however, only represents a fraction of the 150 buildings included on the list this year. In other words, if you have photos you'd like to share, we'll do our best to add them this post over the course of the day. Lead photo by Florence Chan.
