I see the Jamaica Plain branch of the Boston Public Library a lot. Both morning and evening, the lights on for no apparent reason even though no one can enter it yet.
When I first lived near the library, I never went inside except for (I think) one poetry reading with Christopher Kain. It wasn't until I moved to South Boston that I ended up renting space there for Walter Howard's memorial open mic.
When the pandemic is over, the library is on my list of places to visit.
