Who get the great work bonus?

[fireonmyhand]

Am I the liege going to get the bonus or my vassal who has the province?

 

[Serenity84]

Playing Byzantium I upgraded the Mausoleum and got the bonuses

Local effects i.e tax modifier, extra troops only effect the county. However everything else i.e. new minor titles, opinion bonuses, artifacts, extra decisions etc all go to the top liege.
