Yeah, they really should just fold anything Fort Calgary related to Heritage Park, and redevelop the whole area into a cool festival/athletic park or something. I work across the street, and LOVE history, yet still can't muster up the energy to visit this place. Heritage Park does feel more like a theme park, but I think they do a great job.
The last time I was at the Glenbow was to see the Vivian Maier exhibit just before Covid hit. I thought it was pretty great. I actually didn't mind the older collections either, but agree it felt a bit stuffy and dark. I'm hoping the Glenbow turns into something closer to what the Royal Alberta Museum in Edmonton is. As much as I hate that city, that museum is pretty solid.
Efficiency wise, it basically should probably come to this:
Heritage Park = Old timey Calgary/Alberta/Indigenous history
Glenbow = Established Culture/History/Classical Art museum and bigger travelling exhibits of classical art. Ie our "Museum of Natural History".
Contemporary Calgary (maybe merged with Esker?) = Modern art + travelling exhibits of Modern/Contemporary art. Ie. Our MOMA. Ideally they could find a way to exhibit the University of Lethbridge's Modern art collection.
NMC = Anything, everything, music. Gotta find some way to make it more enticing for repeat visits though.
