Earlier this week I took iPhone photos of the Bike Library and its Googie-style building. I hoped Instagram filtering would capture the retro-futurist pitch of the building's roof-lines, and maybe it did. The Instagram filtering worked well enough for me to take on another great example of attention-grabbing commercial architecture in Fort Collins: the old Safeway grocery store and its wavy roof at 425 South College Avenue.

We can identify Safeway buildings from the 1960s through the 1980s based on their vaulted roofs. A swooping grocery store roof-line is synonymous with Safeway, and it practically defines our daily-life routine of buying groceries. Still, those associations are fading, as the architecture of Safeway stores changes and old Safeway stores find new tenants. For example, Sports Authority now occupies the old Safeway store in Fort Collins.

The old Safeway store in Fort Collins is an example of the Marina style of Safeway building, where a central vaulted roof rolls out on either side, as symmetrical upward slopes. The undulating roof-line reproduces the profile of the foothills behind the building – and a field of parking lot rolls out in front. My Instagram photos, below, which were taken on Thursday morning, aim to capture that.
