Regret is one of our least flattering poses as preservationists. It’s eye-catching, sure, and can be galvanizing (c.f. demolition of Penn Station). But mourning dead landmarks doesn’t usually have such catalytic effects. Plus, it marginalizes preservation successes and takes energy away from keeping extant buildings maintained and occupied.
Still, there’s always a market for a hearty dose of nostalgia, as on this Places Not Forgotten Inquirer site. To be fair, it also includes endangered buildings “on the cusp of being lost to time.”
