My cousin the bell tower, in spite of their frequent ringing, is mute on the subject of access. There’s a clue (bit.ly/bells-clue) but it predates renovation. Here’s a bit of a virtual tour: bit.ly/BCM-gasson, and another: bit.ly/burnsblog-gasson. I’ll see what else my assistants can find out & update you if there’s news.
Gasson Hall was always a little tight-lipped but got even more so after the renovation in 2007 when its bells were silenced temporarily. Since Gasson isn’t talking, I’ve had my assistants poke around a little. There’s a clue in this Boston College Magazine alumni-submitted story: bit.ly/bells-clue, but as the story predates the renovation, there might not be a door ajar, and you’d probably still have to watch out for the laser-activated alarm. I recommend getting a campus job with facilities. Those folks know everything. But you’ll have to earn their trust before they share.
