Well in Paris the “Caves Saint-Sabin” spring to mind, the venue actually is some catacombs so you can’t go a lot more gothic then that. Been there a couple of times, enjoyed it. Music’s typically also more gothic then minimal, though. Unfortunately I couldn’t spot anything for the time mentioned yet.
There also was an event called “Carnage Dream” every 1st Saturday of the month, but the website is down at present, so no idea if that one still exists.
La Locomotive is rather mainstream, but there might still be something on.
A world-wide resource for dark clubs/events is to be found at , however under the headline “gothic” (even if it’s electro or whatever clubs).
Hope that helped 8)
