Really interesting museum
The Museum of Byzantine Culture in Salónica is certainly full, with multiple rooms, many interesting elements on exhibit, very nice to visit in terms of functionality and viewing the material, yet there are some points that are quite uncomfortable. For example, as in all museums, you're not allowed to use flash, but in this museum you can only photograph the exhibits, not people. If you take a photo of someone, the guards shout out "No flash! No people!" and make you erase the picture. It's even worse if you ask why you can not take pictures with people they'd give a reason, but in most cases, they do not know or they say they believe it is because it is not normal for a single person to take a picture with a work of art (no exaggeration).
