GDP per industry and per region in Europe
Eurostat is the way to go.

Website: http://ec.europa.eu/eurostat (advised that you start from here to get where you want to be because then you see what is actually available)

GDP specifically (I think this is not what you need exactly - GDP per country over time - but its a starting point.): http://ec.europa.eu/eurostat/web/national-accounts/data/main-tables

Keep it in mind. Need Europe+numbers? Eurostat.
