Here, in Pollensa, Mallorca, the two main galleries situated in Plaza Major are closing/closed; one, a least, is becoming a restaurant with the other probably doing the same. Both sold paintings, and even that's diving to Hades. Others here, smaller, have opened and closed and become something else. I suspect that's because this is a tourist town; might be very different in Palma or Barcelona or Madrid. I guess you need yuppies and other people with a social something to prove.
Hope it works for you guys, though.
