Most Torontonians are familiar with Santiago Calatrava's Allen Lambert Galleria at Brookfield Place in the Financial District. The massive atrium, which connects Yonge and Bay Streets, has been a favourite photo stop for tourists and locals alike since seeing completion over 20 years ago, and its iconic aesthetic has led to the affectionate nickname "the crystal cathedral of commerce". As one of the most photographed locations in Toronto, photographers often put their own spin on the classic shot, using creative angles and processing techniques to set their shot apart. Today's Photo of the Day, showing a worm's-eye perspective of the famed angle, comes to us from "artland" via the UrbanToronto Flickr Pool.
