Once upon a time, Venice was affordable. Heck, when I was young it was on the cheaper side.
Those days are long gone. But loss of affordable housing doesn't happen on its own.
Beyond Baroque is currently presenting Where Has All the (affordable) Housing Gone? In Search of Lost Rent-Control Housing in Venice. More than 270 rent-controlled buildings have vanished from the market in Venice, many (but not all) via the Ellis Act.
The exhibit runs until November 4, but the event page invites attendees to "Join us for Tours and Conversation: October 14 & 28, 1-5pm", so if that interests you, clear your calendar for this Saturday or for the Saturday after next.
In the interest of full disclosure, I assisted with one data-related task leading up to this exhibit. I was shocked and dismayed, and you just might be, too.
