Great place to anchor oneself in Galician culture - no pun intended, although there are things in exhibits related to this seafaring people. The exhibits are permanent and rotating. That is part of the appeal, once again, of the ability of Galicia to seem eternally the same yet constantly surprising you with new old facts or simply new tidbits.
The web site is really excellent, and gives an idea of how the exhibits are intended to reflect the local history and culture. The sea, the farm, music, regional dress, crafts, habitat, and much more. And as always, in Galicia, here's the granite, the stones ancient and just really old, written on, sculpted, placed nonchalantly to make you think they required human hands to get there. Even the building that houses the collections is really worthwhile - it was an old convent, probably 13th century, but what you see is from around 1700.
Besides the anthropological exhibits, there are modern art displays at times and exhibits of places like Cabo Verde. Look closely - there is a common thread to all. The museum has recently acquired several personal libraries of local intellectuals, which makes it a cozy and very good resource for researchers in Galician themes. It appears some online access is being created mow.
The Museo do Pobo also has a long standing publication activity.
It might be more fruitful to go the first time with a friend who can lead you around, make sure you see the winding staircase with several layers of spirals (or so it seems), point out the incredible skill of the basket or clog makers represented in the permanent displays, and just wax sentimental over the culture. After that, you can return by yourself to study the parts that interest you the most. For me, it depends on my mood and how much time I have. Some days it's sea, some days it's land and how agriculture was carried out here. Other days it's entertaining to spend time talking to the people who work in the museum. They too have a lot to offer and are usually generous with the information.
