What goes on on Tuesday nights here? I always hear loud music and can see some sort of video being projected onto the face of the building while I'm waiting for my bus.

It's a video projected on the front of the cathedral. It's really nice and free to watch. You should check it out.

How cool! I haven't been able to check it out because my bus home arrives just after the presentation starts. I'll get a friend to drive & check it out w/me soon! Thanks for info, everyone!

Yes, surely Eric is correct. It is a video laser music presentation chronicling the history and culture of San Antonio from ancient times to the present. It is free and presents on Tuesday Friday Saturday and Sunday at 9 p.m. 9:30 p.m. and 10 p.m. . A very unique presentation, don't miss it.

The video tells the history of the area.
